Update to upstream a7b4c5d25aeb

Updates to pick up a build id off-by-one bug fix upstream. Previously
the build ids returned by libunwindstack were missing the final byte.

We update to the commit with the bug fix rather than latest to defer
picking up an upstream change that moves android-base into a separate
repository. That will require additional tooling changes beyond the ones
we've already had to make to for this update.

This CL contains upstream changes for just the files required to build
libunwindstack within Chrome.
