gnome: Use --pkg to pass pkg-config cflags to g-ir-scanner

While g-ir-scanner's compatible -I and -D flags cover what most pkg-config
files use, there's no guarantee that files don't set anything more exotic
that conflicts with the tool's own options.

For a real world example, mozjs-38 has '-include some-header-file.h', which
translates to '--include nclude another-file-to-scan.h' for the scanner;
unless for some reason there's an 'nclude' GIR available on the system,
the target will thus fail.

Avoid this case by pointing g-ir-scanner to the correct pkg-config file
instead of passing any cflags directly.
