w32: Move socketdir to LOCAL_APPDATA

Browse source 
* common/homedir.c (is_gnupg_default_homedir): Use standard_homedir
instead of the constant which makes a difference on Windows.
(_gnupg_socketdir_internal) [W32]: Move the directory to LOCAL_APPDATA.
(gnupg_cachedir): Remove unsued function.

* common/sysutils.c (gnupg_rmdir): New.
* tools/gpgconf.c (main): s/rmdir/gnupg_rmdir/.

That is actually a more correct directory than APPDATA.  This fixes
a problem with installations where the APPDATA is non a network drive
and the resulting socket filename is truncated in our socket helper
function (because we use sockaddr also for our local socket
emulation on Windows).

LOCAL_APPDATA is expected to be on the local box and thus in the
majority of cases the resulting socket file name will be short enough.
