glamor_egl: Properly free resources on init-error and exit

Browse Source 
glamor_egl_init() was not undoing any of the init steps on init error,
add an glamor_egl_cleanup() function and use this both on error and on exit
to cleanup the various resources.

Even on a clean exit eglTerminate() was not being called, causing the fd
dup()-ed by eglInitialize() to stay open, call eglTerminate() from the new
glamor_egl_cleanup() to fix this.
