c0ffceccf9 Remove dependency on zipalign.
Roll our own version of zipalign so that we can break the dependency
on the build tools zipalign. This breaks the transitive dependency
on androidfw so that building bionic unit tests in brillo works again.

Also modify the DlExtTest.ExtInfoUseFdWithOffset test so it dynamically
gets the offset of the shared library inside of the zip instead of
hard-coding the value.

aef719510a Support loading shared libraries from zip files
Add code to support loading shared libraries directly from within
APK files.

Extends the linker's handling of LD_LIBRARY_PATH, DT_RUNPATH, etc
to allow elements to be either directories as normal, or ZIP
format files.  For ZIP, the ZIP subdirectory string is separated
from the path to file by '!'.

For example, if DT_NEEDED is libchrome.so and Chrome.apk is the
Android ARM APK then the path element

  /system/app/Chrome.apk!lib/armeabi-v7a

would cause the linker to load lib/armeabi-v7a/libchrome.so
directly from inside Chrome.apk.  For loading to succeed,
libchrome.so must be 'stored' and not compressed in Chrome.apk,
and must be page aligned within the file.

Motivation:

667853d477 Build dlext_testzip as custom module.
Use $(BUILD_SYSTEM)/base_rules to build it as custom module, so that
it's exposed to utilities like mm/mmma etc.
