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.*'
