meta-phosphor: mmc-init: Abide by init= from kernel commandline

Use of e.g. systemd-bootchart[1] requires that we override the path to
`init` on the kernel commandline. Currently `mmc-init.sh` hard-codes
`/sbin/init` as the init path and this prevents such boot analysis.

Generalise option processing for the kernel commandline so we can
extract the value for arbitrary key-value pairs and build the required
functionality on top of this new abstraction.
