Some tests have strict requirements on the filesystem permissions
for certain files and directories. This adds a regress/check-perm
tool that copies the relevant logic from sshd to exactly test
the paths in question. This lets us skip tests when the local
filesystem doesn't conform to our expectations rather than
continuing and failing the test run.

Fix some problems with the keys-command test:
- use string comparison rather than numeric comparison
- check for existing KEY_COMMAND file and don't clobber if it exists
- clean up KEY_COMMAND file if we do create it.
- check that KEY_COMMAND is executable (which it won't be if eg /var/run
is mounted noexec).
