update various gentoo bits

Update an rc-update call to only be made if running openrc instead of
all gentoo profiles (systemd does not have rc-update).

Add python3-pyyaml package mappings.

Update serial console to support multiple arches.

Update open-iscsi and open-isns keywords (looks like upstream merged
some musl fixes).

Update the kernel and initramfs file name globs for the
gentoo-kernel-bin usage.
