update grub2 file name

Some higher versions of grub2 (e.g. 2.05 or 2.06-rc1) use
grub.cfg-01-MAC, while another lower versions of
grub2 (e.g. 2.04) use MAC.conf, so we generate both paths
in order to be compatible with both.

Fixes the problem about grub2 config file. Some higher versions of
grub2 (e.g. 2.05 or 2.06-rc1) use grub.cfg-01-MAC, while another
lower versions of grub2 (e.g. 2.04) use MAC.conf, so we generate
both paths in order to be compatible with both.
