expand: Fix glibc glob(3) support
It's been a while since we disabled glob(3) support by default. It appears to be working now, however, we have to change our code to detect the no-match case correctly. In particular, we need to test for GLOB_NOMAGIC | GLOB_NOCHECK instead of GLOB_MAGCHAR. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
