Subject: tests: Skip assert-msg-test.py if gdb fails

Similar to commit 6e44151bf74d, skip the test if gdb is unable to read
/proc/PID/mem, which gdb does as a fallback if ptrace is unavailable.

This allows the test to skip when run under Gentoo's sandbox.

(cherry picked from commit 19a8df9d8bff279a55b0fa3bb7ba4fbf7fcbefa8)
