powerpc: Fix handling of scv return error codes [BZ #27892]

When using scv for templated ASM syscalls, current code interprets any
negative return value as error, but the only valid error codes are in
the range -4095..-1 according to the ABI.

This commit also fixes 'signal.gen.test' strace test, where the issue
was first identified.
