build: Fix for bash quoting in supermin-split.sh.in (RHBZ#566511 RHBZ#566512)

Bash changed how the =~ operator worked, see bash FAQ question
E14 http://tiswww.case.edu/php/chet/bash/FAQ and
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487387#25
(RHBZ#566511).

This also stops stray "builddir" (yum database) files being
incorporated into supermin hostfiles in Koji (RHBZ#566512).
