Rephrase `fs::symlink_metadata` error

[marcospb19]

This is 100% a nitpicky ask but I got this error message:

failed to query metadata of symlink `/tmp/ ... 

It was a call to fs_err::symlink_metadata.

fs-err/src/errors.rs

Lines 96 to 98 in 62640b6

	E::SymlinkMetadata => {
	write!(formatter, "failed to query metadata of symlink `{}`", path)
	}

I think it should have the same error message as the regular metadata call.

fs-err/src/errors.rs

Line 82 in 62640b6

E::Metadata => write!(formatter, "failed to query metadata of file `{}`", path),

I know symlink_metadata makes it sound like it's supposed to refer to reading a symlink, like read_link.

But that method actually exists so that we can check file metadata without traversing symlinks, it is a different behavior, but it doesn't imply that the given path is actually a symlink.

You might just want to check for file types, but you want 3 options instead of just 2, without really expecting that file to be a symlink.
