t3700: fix broken test under !SANITY

An "add --chmod=+x" test recently added by 610d55af0f ("add: modify already added files when --chmod is given", 2016-09-14) used "xfoo3" as a test file. The paths xfoo[1-3] were used by earlier tests for symbolic links but they were expected to have been removed by the time the execution reached this new test. The removal with "git reset --hard" however happened in a pair of earlier tests, both of which are protected by POSIXPERM,SANITY prerequisites. Platforms and test environments that lacked these would have seen xfoo3 as a leftover symbolic link that points at somewhere else at this point of the sequence, and the chmod test would have given a wrong result.
