When GIRs are built on macOS with Meson, the shared-library= entry in the GIR incorrectly prepends @rpath to the library name.

(Example taken from the Meson bug)

I tracked this down to giscanner/shlibs.py:_resolve_non_libtool():

if platform_system == 'Darwin':
    args.extend(['otool', '-L', binary.args[0]])

otool -L here will return @rpath/libatk-1.0.0.dylib

Then it extracts the library name with this regex: "([^\s]*lib*%s[^A-Za-z0-9_-][^\s\(\)]*)". This will erroneously include the leading @rpath in the result.

This doesn't happen with Autotools because it does not use @rpath in install_name. Meson does.
