Revert "Don't define |r_debug| and |link_map| on Android releases 21 and later"

Browse Source 
This reverts commit 0fc6d0c8df because it
does not compile in Chromium due to the following error:

In file included from ../../breakpad/src/client/linux/minidump_writer/linux_dumper.h:43:0,

> Don't define |r_debug| and |link_map| on Android releases 21 and later
>
> NDKs for Android 21 and later have the data structures |r_debug| and
> |link_map| defined in their header files. Defining them multiple times
> generates a compiler error.
>
> This patch protects both data structures from definition on Android 21
> and later.
