Print type name when printing Rust slice
The recent change to how unsized Rust values are printed included a
small regression from past behavior. Previously, a slice's type would
be printed, like:
(gdb) print slice
$80 = &[i32] [3]
The patch changed this to just
(gdb) print slice
$80 = [3]
This patch restores the previous behavior.
