build-sys: do not make qemu-ga link with pixman

Since commit d52c454aad ("contrib: add
vhost-user-gpu"), qemu-ga is linking with pixman.

This is because the Make-based build-system use a global namespace for
variables, and we rely on "main.o-libs" for different linking targets.

Note: this kind of variable clashing is hard to fix or prevent
currently.  meson should help, as declarations have a linear
dependency and doesn't rely so much on variables and clever tricks.

Note2: we have a lot of main.c (or other duplicated names!) in
tree. Imho, it would be annoying and a bad workaroud to rename all
those to avoid conflicts like I did here.
