riscv64: Avoid F and V instruction generation

As reported in issue #299, the latest RHF goes boot loop since `nightly-2023-06-07` Rust toolchain. This is because the recent Rust generates code that includes F and V extensions, which we need to enable these features on startup. This commit disables generation of these extensions as a workaround. Signed-off-by: Akira Moroo <[email protected]>
