Use void(void*) instead of decltype with sk_free.

Unfortunately, boringssl also declares a function named sk_free making
decltype give an error since the function is overloaded if both Skia and
BoringSSL headers are included in the same TU (as happens in ChromeOS
builds). In theory one can use decltype and specify which overload to
use, but this is far more verbose than just specifying the type.
