userenv: Fix setting the ALLUSERSPROFILE environment variable.

Since 27edd4e35c1eb3827dfb20578733242d9ed3d460 ALLUSERSPROFILE is set to
C:\users\C:\users\Public. This is because the expanded registry
value of "Public" is appended to "ProfilesDirectory" and "Public" expands
to a full path. AllUsersProfile, used before this commit, expanded to just
"Public".
