rust: kbuild: use host dylib naming in rusttestlib-kernel

There seems to have been merge skew between commit b2c261fa8629 ("rust:
kbuild: expand rusttest target for macros") and commit 0730422bced5
("rust: use host dylib naming convention to support macOS") ; the latter
replaced `libmacros.so` with `$(libmacros_name)` and the former added an
instance of `libmacros.so`. The former was not yet applied when the
latter was sent, resulting in a stray `libmacros.so`. Replace the stray
with `$(libmacros_name)` to allow `rusttest` to build on macOS.

Fixes: 0730422bced5 ("rust: use host dylib naming convention to support macOS")
