Fix makefile target to run test when there are some shell script.

SImply do not include SHEL_TESTS among RUNTIME_TESTS, because
shell script have a their own rule to be excuted. 
The runtime evaluation by using the $(shell ...) command doesn't work
due to immediate expansion of shell function.
Currently only nptl tests have shell script, so this problem have been never
discovered before.
