package/socat: fix printf feature detection

Browse Source 
socal configure uses AC_TRY_RUN to detect printf features. This does
not work for cross compilation.

All C libraries we use support C99 snprintf. Only glibc and uClibc
support the deprecated Z modifier.

These issues were noticed by an inspection of configure.ac.
