classabbyamp 79f29ed53e bin/xbps-pkgdb: use -errno values for error states
...when checking a package. This will give more relevant information
than before, removes a message that is misleading in many cases, and
allows for some minor simplification.

before:
```
$ doas xbps-pkgdb runit-void; echo $?
ERROR: runit-void: hash mismatch for /etc/runit/2.
ERROR: runit-void: files check FAILED.
Failed to check `runit-void': Operation not permitted
1
```

after:
```
$ doas xbps-pkgdb runit-void; echo $?
ERROR: runit-void: hash mismatch for /etc/runit/2.
ERROR: runit-void: files check FAILED.
1
```

this does not change the behaviour of `xbps-pkgdb -a`
