Subject: [PATCH] Fix unquoted string in --class

References: bnc#788322
Patch-Mainline: no

If GRUB_DISTRIBUTOR contains special character such as '$', it would
lead to syntax error by the grub2-script-check even though user
correctly quote them in single quotes.

The cause is that grub2 scripts use not quote the strings from
GRUB_DISTRIBUTOR in --class options thus keywords interpreted by the
script parser. The fix is to add single quote to the string.
