common.h: bitmaps: Provide PRBITMASK

This is a printf format specifier, a la PRIx32 et al. This avoids us having to write %#x explicitly, which would be annoying if bitmask_t ever changed its type. No use sites introduced in this commit, so no functional change yet. Signed-off-by: Ian Jackson <[email protected]>
