test-skeleton.c: Do not set RLIMIT_DATA [BZ #19648]
With older kernels, it is mostly ineffective because it causes malloc to switch from sbrk to mmap (potentially invalidating malloc testing compared to what real appliations do). With newer kernels which have switched to enforcing RLIMIT_DATA for mmap as well, some test cases will fail in an unintended fashion because the limit which was set previously does not include room for all mmap mappings.
