selftests/bpf: Enable cross platform testing for vmtest

Browse source

Add support cross platform testing for vmtest. The variable $ARCH in the
current script is platform semantics, not kernel semantics. Rename it to
$PLATFORM so that we can easily use $ARCH in cross-compilation. And drop
`set -u` unbound variable check as we will use CROSS_COMPILE env
variable. For now, Using PLATFORM= and CROSS_COMPILE= options will
enable cross platform testing:

  PLATFORM=<platform> CROSS_COMPILE=<toolchain> vmtest.sh -- ./test_progs
