gpsd: Fix gpsd Yocto pyro build for read only rootfs

Browse Source 
Attempting to include gpsd on Yocto pyro with IMAGE_FEATURES including
read-only-rootfs results in an error:
"The following packages could not be configured offline and rootfs is
read-only"

This stems from a failure during the do_rootfs steps where the /etc/init.d/gpsd
file is missing during the call to update-rc.d.

This happens because the /etc/init.d/gpsd file is installed during
package install for gpsd-conf instead of gpsd, and the default value for
INITSCRIPT_PACKAGES is PN.  To resolve, specify INITSCRIPT_PACKAGES as
gpsd-conf instead.

Also, as suggested on the Yocto mailing list, refactor to inherit
update-alternatives and use this to replace the postinst and postrm
steps.
