Fixed incorrect reliance on errno in emubd

Browse Source 
When running the tests, the emubd erase function relied on the value of
errno to not change over a possible call to unlink. Annoyingly, I've
only seen this cause problems on a couple of specific Travis instances
while self-hosting littlefs on top of littlefs-fuse.
