error: misleading indentation; statement is not part of the previous 'if' [-Werror,-Wmisleading-indentation]

Before the output looked like this, if a public key was not found:
```
testing key 1 (IDKey2)
RSA-X-509: OK
RSA-PKCS: OK
testing key 2 (IDKey3)
couldn't find the corresponding pubkey for validation
couldn't find the corresponding pubkey for validation
RSA-X-509: RSA-PKCS: testing key 3 (IDKey4)
couldn't find the corresponding pubkey for validation
couldn't find the corresponding pubkey for validation
```
Now:
```
testing key 1 (IDKey2)
RSA-X-509: OK
RSA-PKCS: OK
testing key 2 (IDKey3) -- can't find corresponding public key, skipping
testing key 3 (IDKey4) -- can't find corresponding public key, skipping
```
Before it was a bit confusing, e.g.:
```
testing key 1 (2048 bits, label=IDKey2) with 1 signature mechanism
RSA-X-509: OK
couldn't find the corresponding pubkey
testing key 2 (0 bits, label=IDKey3) with 1 signature mechanism -- can't be used to sign/verify, skipping: can't obtain modulus
```
The error message in line 3 is for IDKey3 and not for IDKey2.
With this patch the output is aligned with `test_verify`:
```
testing key 1 (IDKey2) with 1 mechanism
RSA-X-509: OK
testing key 2 (IDKey3) with 1 mechanism -- can't find corresponding public key, skipping
```
* pkcs11-register: Fixed detection of already registered OpenSC
Anny configuration of onepin-opensc-pkcs11.so and opensc-pkcs11.so
should be enough to skip registering the default module again.
* Use onepin module for generic NSS DB
fixes https://github.com/OpenSC/OpenSC/issues/1818
May have the disadvantage that some other programs that use NSS don't
see the signature keys. However, we currently only know for sure that
Chromium is using the generic NSS DB.
opensc-tool: for options --version, --list-readers, -D, etc. we do not
need to connect card/reader. This removes unnecessary error messages
if card is not present in card reader or if reader is not available.
util.c: use symbolic error codes, pass error codes to caller without change.
Option -r is used in other opensc tools to specify card reader. pkcs15-tool
uses -r to specify cerfificate. This fix intorduces warning message if -r
is used, and for future versions of pkcs15-tool -r is used to specify
reader.
If card driver fails to connect to card, 'opensc-tool -a' may fail to print
ATR even if ATR is available from card reader. Before use of card driver,
do only card reader connect, then print ATR. Only if it is neccesary, use
card driver for the rest of opensc-tool functions.
