capability: use /proc/sys/kernel/cap_last_cap

This file was introduced with linux-3.2, use it instead of probing for it
via prctl(PR_CAPBSET_READ).

For now, keep the old code for backwards compat. We can drop it once 3.2
is our lowest requirement.

The test-cap-list code is extended to verify cap_last_cap() is the same as
we'd get via prctl probing and /proc.
