Subject: [PATCH] Fix run-tests.php for explicitly given test cases

The recent improvement to list skipped extensions explicitly[1] missed
to properly initialize `$ignored_by_ext` for the case where an explicit
set of test cases are given; this was not a problem previously, since
the undefined *global* variable was coerced to int.  We fix this by
initializing the variable earlier.
