send_bits_trace: placate -Wformat

value, which can be uint64_t, is printed using %llx, which, strictly
speaking, is not correct, and triggers -Wformat.

Since we don't really know what type value can have (send_bits_trace
is a macro), don't use <inttypes.h>, but rather cast it to long long.
Also cast length to int in order to prevent similar issues in the
future.
