selftests/bpf: Correctly display subtest skip status

[ Upstream commit f667d1d66760fcb27aee6c9964eefde39a464afe ]

In skip_account(), test->skip_cnt is set to 0 at the end, this makes next print
statement never display SKIP status for the subtest. This patch moves the
accounting logic after the print statement, fixing the issue.

This patch also added SKIP status display for normal tests.
