[OE-core] [PATCH 3/3] sstatesig: fix to support unincremental locked signature dump

[Hongxu Jia]

The condition of incremental locked signature dump is an
existed locked sig file is required and it is also the
dump sig file.

But if they are not the same file or simply no locked sig
file required, it should be unincremental.

In unincremental dump situation, we should write the locked
sig file rather than append.
