kunit: tool: show list of valid --arch options when invalid
Consider this attempt to run KUnit in QEMU:
$ ./tools/testing/kunit/kunit.py run --arch=x86
Before you'd get this error message:
kunit_kernel.ConfigError: x86 is not a valid arch
After:
kunit_kernel.ConfigError: x86 is not a valid arch, options are ['alpha', 'arm', 'arm64', 'i386', 'powerpc', 'riscv', 's390', 'sparc', 'x86_64']
This should make it a bit easier for people to notice when they make
typos, etc. Currently, one would have to dive into the python code to
figure out what the valid set is.
