[LTP] [PATCH v1 1/1] runltp: Enable POSIX regex support for SKIPFILE (-S)

[Jan Polensky]

Enhance the SKIPFILE (-S) option to support POSIX regular expressions, allowing
users to skip groups of tests using concise patterns instead of listing each
test individually.

Previous usage:
	cat > skip_file <<-EOF
		oom01  # reason foo
		oom03  # reason foo
		oom04  # reason foo
		oom05  # reason foo
		special_a # reason bar
		special_b # reason bar
	EOF

New usage:
	echo > skip_file <<-EOF
		oom0[13-5]  # reason foo
		spe.* # reason bar
	EOF

Note: The previous behavior remains fully supported for backward compatibility.
