sm8550-common: init: Override QTI audio rpc daemon service definition

The rpc daemon doesn't support loading ADSP libs from odm partition,
therefore locally set environment variable ADSP_LIBRARY_PATH to allow
that to happen, just like stock does.

Just as a sidenote, during early bringup phase the quick workaround
was to move the relevant blobs from odm to vendor, but then ditched
in favor of copying the stock script. Now, instead of copying it,
simply override the service definition and avoid one duplicate copy
rule.
