ltsp bugs in 009-mock-chroot files

if you choose a specific architecture when creating the client files, the following file is opened, however it has bugs in it:

/usr/share/ltsp/plugins/ltsp-build-client/RHEL/009-mock-chroot

line 21 reads:

MOCKFILE=$option_release_value".cfg

it should be:

MOCKFILE=$option_release_value

If you do not do this, it creates a file called :
/etc/ltsp/mock/epel-6-x86_64.cfg.cfg

Thats wrong.

line 30 reads:

BUILD=${BUILD:-i686}

it should read:

BUILD=${ARCH:-i686}

If the above change is not made, when it tries to execute the setarch command , it then will not work correctly.
