Fix strtoll, strtoul, and strtouq probes to compile under clang++.

The test programs were missing the stdlib.h header, and needed
tweaks to the check() prototype to compile under clang++.  These
changes should be fine for C compilers as well, but they have typically
been more forgiving, so shouldn't be affected.
