[llvm] [FileCheck] Use FILECHECK_DUMP_INPUT_ON_FAILURE only when non-empty

Enable dumping output only if FILECHECK_DUMP_INPUT_ON_FAILURE is set to
a non-empty value.  This is necessary to support disabling it via
POSIX-compliant env(1) that does not support '-u' argument,
and therefore fix regression caused by r366980.
