Ignore relative paths on Unix for data dir (i.e. ./share/keepassxc)

Have you searched for an existing issue?

• Yes, I tried searching and reviewed the pinned issues

Brief Summary

KeePassXC takes a share/keepassxc in current working directory into account before checking for system paths. This happens only on Unix (non-macOS) systems due to this line:

keepassxc/src/core/Resources.cpp

Line 105 in 7811f10

trySetResourceDir(KEEPASSX_DATA_DIR) || trySetResourceDir(QString("%1/../%2").arg(appDirPath, KEEPASSX_DATA_DIR))

This has effects on offline documentation but also system word lists in passphrase generator and could lead to unexpected results.

Steps to Reproduce

1. Open a terminal on a Linux machine
2. Create a local user guide file, e.g. mkdir -p share/keepassxc/docs; echo hi > share/keepassxc/docs/KeePassXC_UserGuide.html
3. Run keepassxc in same working directory
4. Click Help -> User Guide

You will see hi in your browser instead of the expected user guide. Also, please note that KeePassXC also complains about missing translations and unparseable word list on stdout.

Expected Versus Actual Behavior

I would expect that all systems (Linux, Windows, macOS) behave the same and definitely use the system directories, not something found in current working directory

This is there for debugging purposes (and maybe AppImage, not sure) but should be guarded to debug builds perhaps.
