Move implementations to DataSourceBase.h
Some lib*extractors include DataSourceBase.h but are not
linking libstagefright which has the implementation.
This doesn't cause any build issue in normal build, but
it actually matters when NATIVE_COVERAGE=true which uses -O0.
Fixing by moving the implementation to the header.
