sstatesig.py: Improve the SIGGEN_LOCKEDSIGS_TASKSIG_CHECK message
The previous message when signatures didn't match between the metadata
and the locked signatures file, the message output was a bit confusing.
Now the message should be of the form:
The zlib-native:do_install sig is computed to be
53531910a2a7848432da89def942a91a, but the sig is locked to
d25ba9035f7ccb308e51bbe1066e8d27 in SIGGEN_LOCKEDSIGS_t-x86-64
which will hopefully be more useful in understanding the problem.
