[meta-intel] [PATCH] lms7: re-write do_unpack to fix warning

[Saul Wold]

Since the primary tarball unpacks into a non-standard directory create
a do_unpack that sets and resets  to first unpack the primary tarball
and then unpacks the actual src tarball into the correct directory.

This is similar to lsof which has a dual tarball also.

Fixes this WARNING:
WARNING: /srv/hdd/intel/test/tmp/work/corei7-64-poky-linux/lms7/7.1.20-r0/lms-7.1.20 ('S') doesn't exist, please set 'S' to a proper value
