• Use 1 for an exit code instead of -1 with err, errx, and exit
• Add unistd.h for getuid(3)
• Sort #includes

r292546:

• Convert testcase to TAP format
• Use nitems(x) instead of handrolled sizeof(x) / sizeof(*x) macro
• Do not mark count != 0 case with bsde_get_rule_count as a failure; this generates false positives on systems with ugidfw rules set on it

Move mac_bsdextended check up before running the test_libugidfw_strings testcases

I realize that these tests could be run before mac_bsdextended is loaded, but
it would overcomplicate things to special case handle the testcases before doing
the mac_bsdextended(4) feature check

The testcases will be split up so they can be run separately in the near future

r292651:

Delete the comment about running test_libugidfw_strings before testing
mac_is_present so it doesn't accidentally confuse people
