[PATCH 2/2] test/test-lib.sh: separate signaled exit

[Tomi Ollila]

When execution of tests is interrupted by signal coming outside of the
test system itself, output just one line "interrupted by signal <num>"
message to standard output. This distinguishes the case from internal
exit and reduces noise.
