pw_build: Use -ffile-prefix-map by default

By default, Clang and GCC use file paths directly as provided for debug
symbols and macros like __FILE__. This means that binaries produced on
different machines can be different and may include undesireable info
like usernames.

Clang and GCC provide the -ffile-prefix-map option to strip non-portable
prefixes from filenames. Add a config that applies -ffile-prefix-map to
Pigweed builds by default.
