perf script: Use HAVE_LIBXXX_SUPPORT to replace NO_LIBXXX

In Makefile.config, we define the conditional compilation variables
HAVE_LIBPERL_SUPPORT and HAVE_LIBPYTHON_SUPPORT.

To make the C code more consistent, this patch replaces
NO_LIBPERL/NO_LIBPYTHON in C code with HAVE_LIBPERL_SUPPORT/
HAVE_LIBPYTHON_SUPPORT.
