[Vala] [PATCH]Add an option to valac for passing args to pkg-config

[Kder]

I added a feature(command line option) for the vala compiler:

 -p, --pkg-config-args=ARGS         Pass ARGS to pkg-config utility

to pass customized arguments to pkg-config utility.

For example, we can use this to static compile a gtk program with valac:

valac test_static.vala -p "--static --libs gtk+-2.0 gee-0.8" --pkg gee-0.8 --
pkg gtk+-2.0 -X -static

Here is the patch:
