selftests: openat2: don't print total number of tests and then skip

Don't print that 88 sub-tests are going to be executed. But then skip.
The error is printed that executed test was only 1 while 88 should have
run:

Old output:
  TAP version 13
  1..88
  ok 2 # SKIP all tests require euid == 0
  # Planned tests != run tests (88 != 1)
  # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0

New and correct output:
  TAP version 13
  1..0 # SKIP all tests require euid == 0

This change isn't necessary, != 0 makes what we're checking clearer.

It is wasteful to write != 0 when you can achieve the same without it.

I can update the patch by removing it. Please can you provide a reviewed-by
tag for remaining patch?
