perf cpumap: Introduce cpu_map__snprint_mask()
The cpu_map__snprint_mask() generates a string representation of a
cpumask bitmap. For cpu 0 to 11, it'll return "fff".
Committer notes:
Fix compiler warning on some toolchains:
19 fedora:24-x-ARC-uClibc: FAIL
CC /tmp/build/perf/util/cpumap.o
util/cpumap.c: In function 'hex_char':
util/cpumap.c:679:2: error: comparison is always true due to limited range of data type [-Werror=type-limits]
if (0 <= val && val <= 9)
^
cc1: all warnings being treated as errors
Applying patch from Namhyung that makes function receive an 'unsigned
char', that is what the callers are passing to this function.
