Patch that respects lower wl_seat versions

With commit 61f0ed80 the wl_seat requirement was bumped to version 4, instead
of 3 however this will cause GTK+ clients to not work with compositors
supporting a lower wl_seat version.

A better practice would be to min-bound the version requirement.

wl_seat 4 introduces a request for keyboard repeat information.
The code seems to deal with the fact that this information might not be
available, it only need to accept lower versions.

It's not reasonable to expect all compositors have the latest version all at
once, especially considering that a distro might ship a newer GTK+ version and
an older compositor version.
