xserver-xf86-config: Preload graphics driver modules for musl

musl does not support BIND_LAZY intentionally, which means
dlopen will always complain about missing symbols which is what
X does when loading graphics drivers, here we preload the needed
drivers for all emulator machines if libc is musl
