Add files that would normally be generated by the e2fsprogs build system

Add files that would normally be generated by the e2fsprogs build system

Android doesn't run ./configure and friends, so it has to rely on
pre-populated versions of the autogenerated files.

This is somewhat bogus (e.g. hardcoded little-endian reference in
lib/ext2fs/ext2_types.h) and should at some point be fixed, but it's
what Android has always done, not a regression from the 1.41.14 branch.

Also, don't #include config.h which we don't generate (we pass what it
usually contains as -D parameters from Android.mk) anywhere.

Add a new Android.mk file for the quota library.
