kbuild: rust_is_available: remove -v option

[ Upstream commit d824d2f98565e7c4cb1b862c230198fbe1a968be ]

The -v option is passed when this script is invoked from Makefile,
but not when invoked from Kconfig.

As you can see in scripts/Kconfig.include, the 'success' macro suppresses
stdout and stderr anyway, so this script does not need to be quiet.
