[PATCH 1/2] tests/tcg/multiarch: fix code style in function main of test-mmap.c

[Wei Yang <richardw.yang@linux.intel.com>]

This file uses quite a different code style and changing just one line
would leads to some awkward appearance.

This is a preparation for the following replacement of
sysconf(_SC_PAGESIZE).

BTW, to depress ERROR message from checkpatch.pl, this patch replaces
strtoul with qemu_strtoul.
