[Buildroot] [PATCH 1/1] package/ibm-sw-tpm2: fix patch to address musl builds

[Vincent Fazio]

Note, if we don't like this option i've also seen other packages do 
something akin to:

#if ULONG_MAX == 0xffffffff
#define RADIX_BITS 32
#elif ULONG_MAX == 0xffffffffffffffff
#define RADIX_BITS 64
#else
#error "Unsupported radix size"
#endif
