build-sys: check scanf %ms modifier
Without the check libmount builds on systems that has older than 2.7
glibc are silently unsuccessful. The missing %ms modifier will, at
least, result on such system missing output of findmnt and lsblk
commands. If either %ms or %as modifiers are present the libmount
build is disabled.
Based on patch from: Sami Kerola <kerolasa@iki.fi>
