[Offload] Use libc 'hand-in-hand' module to find RPC header (#117928)

Browse Source 
Summary:
We should now use the official™ way to include the files from
`libc/shared`. This required some code to make sure that it's not
included twice if multiple people use it as well as a sanity check on
the directory.
