patch: don't bail when ALLUSERPROFILE is missing

Hi,

On the TSVN list, a user complained that Subversion doesn't work if the
ALLUSERSPROFILE folder is missing. Seems that such a setup is common for
cytrix setups.

The attached patch fixes this issue: if the ALLUSERSPROFILE folder is
missing, the config data is only read from the APPDATA folder (the users
config folder).

The patch also applies cleanly to 1.6.x, so I would recommend to have
this backported too.

Stefan
