gdb.base/coremaker2.c: Fix compilation problems for x86_64 -m32 multilib

There are compilation warnings / errors when compiling coremaker2.c
for the gdb.base/corefile2.exp tests.  Here's the command to use
on x86_64 linux:

make check RUNTESTFLAGS="--target_board unix/-m32" \
           TESTS="gdb.base/corefile2.exp"

These are the warnings / errors - I've shortened the paths somewhat:

gdb compile failed, gdb/testsuite/gdb.base/coremaker2.c: In function 'main':

These were fixed by changing unsigned long long to uintptr_t.

Tested on either rawhide or Fedora 32 with architectures: x86_64,
x86_64/-m32, aarch64, s390x, and ppc64le.

gdb/testsuite/ChangeLog:

	* gdb.base/coremaker2.c: Change all uses of 'unsigned long long'
	to 'uintptr_t'
	(inttypes.h): Include.
