* infra: stop patching llvm-symbolizer
to prevent it from failing to start up with
```
NEW_FUNC[1/1]: llvm-symbolizer: symbol lookup error: /tmp/not-out/instrumented_libraries/lib/x86_64-linux-gnu/libz.so.1: undefined symbol: __msan_va_arg_overflow_size_tls
==45==WARNING: external symbolizer didn't start up correctly!
```
Closes https://github.com/google/oss-fuzz/issues/5349
* infra: reformat patch_build.py with yapf
to make the presubmit check happy
* Update infra/base-images/all.sh
Add build of base-sanitizer-libs-builder and msan-libs-builder to this
shell script.
* msan: Don't warn on un-instrumented standard libs
These libraries do not need to be built with instrumentation, because
MemorySanitizer includes interceptors for them.
* Fix indentation
* Add missing docstrings
* Fix unused variable
* Fix invalid names
* Install python-apt on CI
* Revert "Install python-apt on CI"
This reverts commit d3da49cf90.

-z should precede a keyword, not a long option
* Fix use of xrange
* Style fixes, compiler_wrapper
* Fix apparent error in compiler_wrapper_test.py
Similar to the previous error, the test case would pass "-z
--no-undefined" to the linker. "-z" only has an effect when it is
followed by a keyword, otherwise ld ignores it and prints a warning
message. In this test case, "-z" and "--no-undefined" were passed in two
separate "-Wl," compiler arguments, but they reflect a common issue.
* Add missing license header
* Rename more functions
* Better name for global variable
* Rename methods of Package
* Rename functions in msan_builder.py
