crypto: x86/sha1 - fix possible crash with CFI enabled

sha1_transform_ssse3(), sha1_transform_avx(), and sha1_ni_transform()
(but not sha1_transform_avx2()) are called via indirect function calls.
Therefore they need to use SYM_TYPED_FUNC_START instead of
SYM_FUNC_START to cause their type hashes to be emitted when the kernel
is built with CONFIG_CFI_CLANG=y.  Otherwise, the code crashes with a
CFI failure (if the compiler didn't happen to optimize out the indirect
calls).

Fixes: ccace936eec7 ("x86: Add types to indirectly called assembly functions")
