commit 8e7ed89978868fc464759257b687d39ce0a24daf

Replace pre-built 7z SFX module for installers with source code for same.

This SFX module for installers is built as part of the chromium build
so that the resulting binary can take advantage of mitigations used in most
of chromium's code.  The pre-built module did not pass the checks in
tools/checkbins/checkbins.py whereas the module as built with chromium does.
