Revert of stack: Adjust Pre-M Android incorrect debuggerd addresses. (patchset #8 id:140001 of https://codereview.chromium.org/1412223008/ )

Original issue's description:
> stack: Adjust Pre-M Android incorrect debuggerd addresses.
>
> Code location addresses printed by debuggerd in pre-M Android
> are wrong where relocations are packed, because the libunwind
> on these targets does not understand non-zero min vaddrs in
> ELF LOAD segments.
>
> Fix by searching the APK staging directory for libraries with
> packed relocations, and adjusting the tombstone data on pre-
> processing so that code addresses printed for these libraries
> by debuggerd are offset by the min vaddr of the library that was
> included in the APK.
>
> This feature is hidden behind a new --packed-relocation-adjustments
> flag, and defines a new --chrome-apk-dir flag that can be used
> to indicate the location of the APK staging directory (defaults
> to ../chrome_apk/ within the chrome-symbols-dir).
>
> Uses the 'Build fingerprint' in the tombstone file to try to
> auto-detect whether packed relocation adjustment should be
> applied (that is, if the target is running pre-M Android).
