[PATCH 4/4] rust: Use 'lbasename()' consistently.

[Iain Sandoe]

The amends the remaining case in the rust code to use the libiberty
lbasename() instead of the (potentially variably-behaved) system
'basename()'.

gcc/rust/ChangeLog:

        * metadata/rust-export-metadata.cc
        (PublicInterface::write_to_path): Use 'lbasename()' instead of
        'basename()'.
