resolve symlinks passed to -C

"meson setup" is resolving symlinks for the build directory in
validate_core_dirs.  For consistency with it, do the same when
the build directory is passed via -C to devenv, dist, init, install
and test.

This ensures for example that the path to test dependencies is
computed correctly in "meson test".

Fixes: #8765
