We want to know the inode of the FD that was mmaped so that we can check
the requested inode when processing the address map from a particular
process.
We still want to load it into the cache as it could get used by other
symbols/mmap regions, but don't return the ELF if it won't match an inode
or build-id check. Rely on other fallbacks to create fallback symbols
for those use cases.
We need to separate a number of concerns here, such as debug-dirs within
the process namespace vs global debug-dirs (external symbols on a developer
workstation vs IoT/Laptop/VM/alternate-device).
That means we need to be able to resolve paths via the mount namespace of
the process as it was seen in the capture file.
Additionally, we need to follow .gnu_debuglink section headers so that we
can associate the version with symbols with the ELF that is loaded from
the processes SysprofAddressLayout.
