[PATCH] Install recently added tests

[Vladimir Zakharov]

Hello!

r323275 added basic tests for chflags, mkdir, rcp and rmdir. But these
tests are not installed to /usr/tests.

# kyua test -k /usr/tests/Kyuafile bin/chflags
Results file id is usr_tests.20170929-195409-880951
Results saved to /root/.kyua/store/results.usr_tests.20170929-195409-880951.db
kyua: W: No test cases matched by the filter 'bin/chflags'.
# ls /usr/tests/bin/chflags/
#

Attached patch fixes this problem.
