selftests/bpf: Fix test_progs's parsing of test numbers 

When specifying disjoint set of tests, test_progs doesn't set skipped test's
array elements to false. This leads to spurious execution of tests that should
have been skipped. Fix it by explicitly initializing them to false.

Fixes: 3a516a0a3a ("selftests/bpf: add sub-tests support for test_progs")
