Subject: Patch #551960: Add check for setrlimit() support

test_resource calls resource.setrlimit() to change the file size limits.
This fails on Cygwin, which supports setrlimit() and getrlimit(), just not
changing that particular setting. (The same would apply to any other
platform that has those functions but not that particular feature.)

Since getrlimit() works and setrlimit() can be used for other reasons, a
check for ValueError was added to that part of the test.
