utils: osmo_bcd2str(): fix applying non-zero offset to null pointer

This can be seen when building with CC=clang:

utils.c:150:22: runtime error: applying non-zero offset 100 to null pointer
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior utils.c:150:22 in
utils.c:150:33: runtime error: addition of unsigned offset to 0x000000000064 overflowed to 0x000000000063
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior utils.c:150:33 in

The *dst pointer may be NULL (e.g. bcd2str_test() is passing it).
This makes tests/utils/utils_test fail.  Let's fix this.
