Remove local copy of android_filesystem_config.h

...present in sony/msm8226-common

* We added the ids for sony_ta and sony_idd
* sony_idd isn't needed
* replace sony_ta with system and tighter perms

Update memory configuration inheritance

* Use 'inherit-product' instead of 'inherit-product-if-exists'
  for the Dalvik heap config, and HWUI memory limits,
  so that the build fails if those files do not exist
* Device doesn't boot with the default values, it
  runs Out-of-memory because of improper configuration
