* tests/test-fprintf-posix3.c: Include "resource-ext.h".
(main): Perform test also when getrlimit and setrlimit don't exist or
when setrlimit of RLIMIT_DATA fails (like on Cygwin). Instead of
limiting the address space size using setrlimit, compare the address
space size before and after the the test.
* tests/test-dprintf-posix2.c: Likewise.
* tests/test-fprintf-posix3.sh: Update skip messages.
* tests/test-dprintf-posix2.sh: Likewise.
