support/testing: use core2duo cpu emulation for TestGlxinfo

Browse Source 
TestGlxinfo fail with a new runtime error:

  # glxinfo -B -display :0
  name of display: :0
  traps: glxinfo[84] trap invalid opcode ip:b73c7027 sp:bf8433c0 error:0 in swrast_dri.so[b6e4c000+64f000]
  Illegal instruction

The x86-core2 Bootlin toolchains are built for a core2 CPU [0],
this means that the Bootlin toolchains may use core2-specific
instructions.

The TestGlxinfo test is setup for BR2_x86_core2, so our
executables will also contain core2 instructions.

However, the default Qemu x86 is not guaranteed to emulate all the
instructions specific to core2, causing runtime issues as reported
above.

A similar issue has been fixed by adding Nehalem cpu emulation on
the qemu command line. See 4f565b5222 ("support/testing: use Nehalem
cpu emulation for TestGrubX8664EFI").

Set core2duo cpu emulation for TestGlxinfo on the qemu command line.
