Fix gfxstream Magma build

- use pkg-config to look for libmagma.a: this is more standard
  in "Linux-distro" style builds rather Meson wrap files.

- don't use magma_fuchsia_log(..) with the gfxstream build.  The
  specialized logger should likely be only needed for Fuchsia
  builds, since mesa_loge(..) already has hooks for Android/Linux.

TEST=compile with related gfxstream patches
