perf tools: Move parse_nsec_time to time-utils.c
Code move only; no functional change intended.
Committer notes:
Fix the build on Ubuntu 16.04 x86-64 cross-compiling to S/390, with this
set of auto-detected features:
... dwarf: [ on ]
... dwarf_getlocations: [ on ]
... glibc: [ on ]
... gtk2: [ OFF ]
... libaudit: [ OFF ]
... libbfd: [ OFF ]
... libelf: [ on ]
... libnuma: [ OFF ]
... numa_num_possible_cpus: [ OFF ]
... libperl: [ OFF ]
... libpython: [ OFF ]
... libslang: [ OFF ]
... libcrypto: [ OFF ]
... libunwind: [ OFF ]
... libdw-dwarf-unwind: [ on ]
... zlib: [ on ]
... lzma: [ OFF ]
... get_cpuid: [ OFF ]
... bpf: [ on ]
Where it was failing with:
CC /tmp/build/perf/util/time-utils.o
util/time-utils.c: In function 'parse_nsec_time':
util/time-utils.c:17:13: error: implicit declaration of function 'strtoul' [-Werror=implicit-function-declaration]

^
util/time-utils.c:17:2: error: nested extern declaration of 'strtoul' [-Werror=nested-externs]
time_sec = strtoul(str, &end, 10);
^
util/time-utils.c: In function 'perf_time__parse_str':
util/time-utils.c:93:2: error: implicit declaration of function 'free' [-Werror=implicit-function-declaration]
free(str);
^
util/time-utils.c:93:2: error: incompatible implicit declaration of built-in function 'free' [-Werror]
util/time-utils.c:93:2: note: include '<stdlib.h>' or provide a declaration of 'free'
Do as suggested and add a '#include <stdlib.h>' to get the free() and strtoul()
declarations and fix the build.
