liblog: add Amazon logging functions for prebuilt compatibility 

Most prebuilt binaries from the Kindle Fire HDX devices link to these
functions.   Adding them here with opt-in CFLAG: AMAZON_LOG

libcutils needs an external reference to these functions as well

liblog implementation follows the same pattern as MOTOROLA_LOG and HTCLOG
