gnulib: import mkstemp

Older versions of MinGW do not support mkstemp causing:

    gdb/unittests/scoped_fd-selftests.c:37:29: error: \
    'mkstemp' was not declared in this scope
       int fd = mkstemp (filename);
                             ^
    gdb/unittests/scoped_fd-selftests.c: In function 'void
    selftests::scoped_fd::test_release()':
    gdb/unittests/scoped_fd-selftests.c:56:29: error: \
    'mkstemp' was not declared in this scope
       int fd = mkstemp (filename);
                             ^

Import mkstemp from gnulib.
