Rename android_info.prop to android-info.prop

android_info.prop is used a prop file input to generate vendor's
build.prop file. Soong autogenerated partition uses an autogenerated
android_info.prop module, this CL makes the make built prop filename similar
to the soong module.

An alternative would be to fix the name of the soong module, but this CL
seems like a better alternative since the naming convention also matches
the android-info.txt file.

Test: verified that vendor/build.prop is similar between make and soong
