Mark Mentovai e956a8252f Port the util library to Android
With this change, it is possible to build crashpad_util for Android with
clang. I built with NDK 13b (clang 3.8) at API 24 (current), API 21
(used by Chrome in 64-bit builds), and API 16 (used by Chrome in 32-bit
builds).

 - In WeakFileHandleFileWriter::WriteIoVec(): Android does not expose
   the IOV_MAX macro, but its value can be obtained by calling
   sysconf(_SC_IOV_MAX).
 - In CloseMultipleNowOrOnExec(): API 21 removes getdtablesize(). Skip
   it, because it returned the same thing as sysconf(_SC_OPEN_MAX),
   which is already consulted.
 - Throughout: Various #ifdefs checking for OS_LINUX have been extended
   to also check for OS_ANDROID. In Chrome’s build_config.h (and thus
   mini_chromium’s), OS_LINUX is not defined when OS_ANDROID is.

This has not been tested beyond building the crashpad_util target.
