[PATCH weston 2/4] weston.pc: Add dependencies for pixman-1 and xkbcommon

[Quentin Glidic]

From: Quentin Glidic <sardemff7+git at sardemff7.net>

Weston headers include pixman and libxkbcommon headers
Using Requires.private means that CFLAGS from pixman-1 and xkbcommon are
added to weston CFLAGS, while LIBS are added in case of static linking
only. This way, plugins does not have to use them, but will need to do
so explicitely if needed, to properly resolve symbols
