Continue removing files after an error

The fix is to skip removing FIFOs had a side-effect of failing to remove
a directory where a skipped file is because the directory is not empty.

The change here is to continue removing files after errors, which is
also helpful in cases when `ios-deploy` fails to remove `/Documents/`
("Error 0xa: You do not have permission."), but still needs to continue
removing what it can from `/Library/`.
