Subject: selftests: mm: fix undeclared function error

Fix the error reported by clang:

In file included from mdwe_test.c:17:
./../kselftest_harness.h:1169:2: error: call to undeclared function
'asprintf'; ISO C99 and later do not support implicit function
declarations [-Wimplicit-function-declaration]
 1169 |         asprintf(&test_name, "%s%s%s.%s", f->name,
      |         ^
1 warning generated.

The gcc reports it as warning:

In file included from mdwe_test.c:17:
../kselftest_harness.h: In function `__run_test':
../kselftest_harness.h:1169:9: warning: implicit declaration of function
`asprintf'; did you mean `vsprintf'? [-Wimplicit-function-declaration]
 1169 |         asprintf(&test_name, "%s%s%s.%s", f->name,
      |         ^~~~~~~~
      |         vsprintf

Fix this by setting _GNU_SOURCE macro needed to get exposure to the
asprintf().
