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  ]

  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.
