[PATCH] modperl_restart_count fix

[Joe Orton]

Current SVN failed -Werror build on x86_64 due to casting between
integers and pointer types:

modperl_util.c: In function `modperl_restart_count_inc':
modperl_util.c:814: warning: cast from pointer to integer of different size
modperl_util.c:817: warning: cast to pointer from integer of different size
modperl_util.c: In function `modperl_restart_count':
modperl_util.c:826: warning: cast from pointer to integer of different size
make[1]: *** [modperl_util.lo] Error 1
make[1]: Leaving directory `/tmp/regressD22607/mp-2.0/src/modules/perl'

This fixes the warnings and passes the test suite, not tested to DTRT
after a restart:
