tests: fix build on rpi with EGL

This patch fixes the compiler errors:

  CC     weston_test_la-weston-test.lo
weston-test.c:34:21: fatal error: EGL/egl.h: No such file or directory

  CC     buffer-count-test.o
buffer-count-test.c:30:21: fatal error: EGL/egl.h: No such file or directory

On rpi, the EGL headers are not in the standard path.
