Second attempt to update lzma_sdk to 9.20

Second attempt to update lzma_sdk to 9.20

The first attempt (r132887) was reverted because the CL
caused build failure on Linux. This is second attempt.

Copied only C code required to open 7z archive files and
uncompress LZMA compression.
CpuArch.c was modified to fix an compile error on 32bit Linux.
Updated chrome/installer/util/lzma_util.cc to follow API
changes.

BUG=None
TEST=installer_util_unittests --gtest_filter='LzmaUtilTest.*'

Hi tommi,

This CL is the second attempt to update lzma_sdk. hbono@ kindly told me how to
fix the compile error which was caused by the previous CL. I modifed MyCPUID()
in CpuArch.c in a similar way of base/cpu.cc.

That is the only difference from the previous CL. I added the diff as
chromium.patch and updated README.chromium. Could you take anther look? (linux
bot is red, but the build succeeded and linux won't run lzma related code for
now).
