Christophe CURIS 3c2fc82b6e WUtil: Avoid memory leak and misbehaviour on internal function 'getuserhomedir' ...

If the function was called more than once with different usernames
it would always return the path for the user on the first call,
which is not what would be expected.

Furthermore, if the function succeeds it allocated memory to save
this path but it was never freed.

The good thing is that the use case for this function is so rare
that it is improbable it was ever called, which explains why it
was never seen.

The new code always behaves as expected, and does not allocate
memory anymore to avoid wasting time and memory for such small
things, which is acceptable because this function is local.
