s3: Add support for make test to use a share dir outside of the prefix dir

Some systems need to have the tdbs (and other files required for samba
to run) on a different filesystem than the share directory that samba
is exporting.

This patch:
- Adds an optional "shrdir" argument to selftest.sh
  - If shrdir is specified it will be used, otherwise the default
    will be used: "<prefix>/tmp"
- Adds a new configure option: --with-selftest-shrdir
- Plumbs shrdir through Makefile.in and configure.in
