[PATCH qemu-server] qemuserver: make base path of libGL and libEGL libraries architecture aware

[Kaiyang Wu <wukaiyang2003@gmail.com>]

'print_vga_device' assumed x86_64 library path to look for 'libGL.so.1'
and 'libEGL.so.1', which leads to missing libraries error regardless of
whether 'libgl1' and 'libegl1' were installed or not, on architectures
other than x86_64.

Make base path of the libraries architecture aware to correctly locate
the libraries on non-x86_64 architectures.
