Andrey Ryabinin 4b2bff7b81 ubsan: Fix nasty -Wbuiltin-declaration-mismatch GCC-9 warnings
commit f0996bc2978e02d2ea898101462b960f6119b18f upstream.

Building lib/ubsan.c with gcc-9 results in a ton of nasty warnings like
this one:

    lib/ubsan.c warning: conflicting types for built-in function
         ‘__ubsan_handle_negate_overflow’; expected ‘void(void *, void *)’ [-Wbuiltin-declaration-mismatch]

The kernel's declarations of __ubsan_handle_*() often uses 'unsigned
long' types in parameters while GCC these parameters as 'void *' types,
hence the mismatch.

Fix this by using 'void *' to match GCC's declarations.
