sys-auth/seatd: Add builtin and server IUSE flags

The builtin flag is for enabling the embedded server backend in libseat that
doesn't require starting a standalone server. It was disabled in the package
previously but some users might want to enable it.

The `server` flag is for enabling the standalone server. It was enabled in
the package previously but some users might want to disable it.
