adjust MACHINEOVERRIDES ordering

FILESPATH is in part built by using MACHINEOVERRIDES and the path
is built working right to left. Use =. instead of .= to prepend
(e6500-64b:qoriq-ppc) to (soc:board).

Take t2080rdb-64b as example, change from:
FILESOVERRIDES="powerpc64:t2:t2080:t2080rdb-64b:qoriq-ppc:e6500-64b:poky"
MACHINEOVERRIDES="t2:t2080:t2080rdb-64b:qoriq-ppc:e6500-64b"

To:
FILESOVERRIDES="powerpc64:e6500-64b:qoriq-ppc:t2:t2080:t2080rdb-64b:poky"
MACHINEOVERRIDES="e6500-64b:qoriq-ppc:t2:t2080:t2080rdb-64b"
