scripts/poky-qemu: fix libGL checks for recent Debian(ish) systems

On 64bit Debian(ish) systems libGL now lives in /usr/lib/x86_64-gnu/, add an
extra test to the qemu script to check for libGL and libGLU in directories
that match this pattern.

Based on commits by Khem Raj (0350be945877b61eb8125663887fd7ed1c3923ab) and
Anders Darander (1927021c78db1a92254785bbc257c00ed2dfcdba) in OE-Core.
