[OE-core] [PATCH V3 06/10] keymaps: fix for systemd

[Chen Qi]

Only install 'keymap.sh' script if 'sysvinit' is in DISTRO_FEATURES.
This is because systemd internally provides a mechanism to implement
the functionality this script tries to implement. Please see
systemd-vconsole-setup.service for more details.

Also we set 'INHIBIT_UPDATERCD_BBCLASS' to "1" if 'sysvinit' is not
in DISTRO_FEATURES.
