lib: optimize sprint_[long_]canframe()

Inspired by the SLCAN rework from Andre Naujoks this patch replaces the
extensive use of sprintf() with simple and efficient ASCII helpers.

valgrind/kcachegrind reported a cyle estimation of about 5.3 million cycles
before and about 1.5 million cycles after the rework (factor 3.55) for the
logging of the exact same CAN content.
