kbuild: Remove check for broken scoping with clang < 17 in CC_HAS_ASM_GOTO_OUTPUT

Browse Source 
Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the check added to CC_HAS_ASM_GOTO_OUTPUT by
commit e2ffa15b9b ("kbuild: Disable CC_HAS_ASM_GOTO_OUTPUT on clang <
17") can be removed, as the issue it detects is guaranteed to be fixed.
