3ec1114a97 selftests/bpf: Replaces the usage of CHECK calls for ASSERTs in bind_perm 
bind_perm uses the `CHECK` calls even though the use of
ASSERT_ series of macros is preferred in the bpf selftests.

This patch replaces all `CHECK` calls for equivalent `ASSERT_`
macro calls.

82cb2b3077 bpf: selftests: Remove libcap usage from test_progs 
This patch removes the libcap usage from test_progs.
bind_perm.c is the only user.  cap_*_effective() helpers added in the
earlier patch are directly used instead.

No other selftest binary is using libcap, so '-lcap' is also removed
from the Makefile.

8c0be0631d selftests: bpf: Fix bind on used port 
The bind_perm BPF selftest failed when port 111/tcp was already in use
during the test. To fix this, the test now runs in its own network name
space.

To use unshare, it is necessary to reorder the includes. The style of
the includes is adapted to be consistent with the other prog_tests.

v2: Replace deprecated CHECK macro with ASSERT_OK

Return 3 to indicate that permission check for port 111
should be skipped.
