rules.d: import the keyboard builtin instead of running it

RUN seems to be used primarily for historical reasons over the more
immediate IMPORT command. As a side-effect, RUN also runs *after* all the
rules have been processed which is not really what we want here - we expect
the device to be updated immediately. Other rules that rely on accurate evdev
axes should be able to assume the axes are already present. So let's use
IMPORT here.

For consistency, the second two rules are split across multiple lines as well.
