Numerous issues caused sim_test to be attempted even though libosmosim was not
built:
In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported.
Furthermore in configure.ac, no value 'yes'/'no' was assigned to the
ENABLE_PCSC variable, only to the enable_pcsc value.
In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have
no effect, regardless (not even when using a variable that should be defined
accurately).
So fix with these steps, similarly to how we do it in openbsc:
In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'.
Export the same using AC_SUBST().
Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add
atlocal to AC_OUTPUT and distclean).
Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to
indicate skipping the test if enable_sim_test isn't 'yes'.
