1. rustc: Ignore fs::canonicalize errors in metadata …

   This commit updates the metadata location logic to ignore errors when
   calling `fs::canonicalize`. Canonicalization was added historically so
   multiple `-L` paths to the same directory don't print errors about
   multiple candidates (since rustc can deduplicate same-named paths), but
   canonicalization doesn't work on all filesystems. Cargo, for example,
   always uses this sort of fallback where it will opportunitistically try
   to canonicalize but fall back to using the input path if it otherwise
   doesn't work.
   
   If rustc is run on a filesystem that doesn't support canonicalization
   then the effect of this change will be that `-L` paths which logically
   point to the same directory will cause errors, but that's a rare enough
   occurrence it shouldn't cause much issue in practice. Otherwise rustc
   doesn't work at all today on those sorts of filesystem where
   canonicalization isn't supported!
