tests/mem_protect: Use minimal libc for kernel.memory_protection 

This test has trouble on qemu_x86_tiny and randomly generates a Double
Fault error. I couldn't get it to reliably run with picolibc as a Double
Fault usually occured before the test completed.

I spent a couple of hours attempting to track this down and found that it
happens when code pages for the main thread get unmapped because the
qemu_x86_tiny intentionally offers very few available PTEs.

Work around this by just using the minimal libc for this test.
