This reverts commit 954a534bc0e7f30e66cc7dfd15ac79544e92671f.
It appears that the concerns from this commit are invalid. The case of
~asdf/ does not have any fallback case, if there is no getpwent on this
system, then there will be simply an error, same for the case of a
missing user. In such a case nothing will be written in the buffer /
returned by eina_vpath. The windows build problem can be
fixed by a simple #ifdef'ing the test code.
