core: Allow vendor odm symlink in framework overlays paths

If odm partition doesn't exist, its contents are put into /vendor/odm
on Treble-enabled devices. Currently, this path is not allowed for
framework overlays which causes boot loop with the following message:

03-08 21:31:32.642  3444  3444 F zygote64: jni_internal.cc:825] JNI FatalError called: (system_server) Not allowlisted (52): /vendor/odm/overlay/<overlay name>.apk
