sysprofd: add proxy support for mmap2/build_id

Browse Source 
We will want to be able to open perf event streams with these options so
that we can get the build-id extracted from an ELF without having to rely
on parsing it at resolution time.

Additionally, it could give us an option for live-decoding at some point
in userspace without having to write the major DWARF capture data to disk.
