xfstests: ignore absolute address in filename in test case 237

[Boris Ranto]

Test case 237 checks for setfacl output. The setfacl can use both
relative address or absolute address for filename.

Following patch ignores the unnecessary part of absolute address and
therefore the test case can pass on systems that output absolute
address:
