[PATCH weston] configure: prevent premature HAVE_GLU check

[Konno, Joe]

When cairo-gl and mesa-glu are present on the system, autoconf successfully
recognizes both. However, I was wondering why weston-screensaver was not
building since autoconf reported all dependencies were met.

Move the mesa-glu PKG_CHECK before the conditional. Additionally, remove
redundant check for enable_egl, as it is implied when GLU is 'yes.'
