cm: init.rc: Fix compcache and cleanup init file

The "import" keyword is only parsed once, for a one shot execution, during
the initial section setup, and before running "on fs". Having an import of
a file that's located in a filesystem other than root will result in an error
like

<3> init: could not import file '/system/etc/init.local.rc' from '/init.rc'

So... any files imported into init need to be moved to the root fs.
While we're at it, move init.rc changes that are specific to CM (and don't
involve modification of preexisting configs) into this file, to ease future
upstream merges (and minimize breakage on devices that override init.rc with
their own variants)

Needs to be paired with the corresponding system/core patch
