Revert "loongarch: add frecipe and relax target feature"

This reverts commit e81df3f3225ce53921a87b9e490959c41b783b02.

Debian: this commit breaks a lot of tests on loong64 since our rustc build is
still based on LLVM-17. This revert should be dropped once we switch over to
LLVM 18.

Bug: https://github.com/rust-lang/rust/issues/114661
