rust: proc-macro2: remove `unicode_ident` dependency
The `proc-macro2` crate depends on the `unicode-ident` crate to determine
whether characters have the XID_Start or XID_Continue properties according
to Unicode Standard Annex #31.
However, we only need ASCII identifiers in the kernel, thus we can
simplify the check and remove completely that dependency.
