perf intel-pt: Fix parsing of VM time correlation arguments

Parser did not take ':' into account.

Example:

 Before:

  $ perf record -e intel_pt//u uname
  Linux
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.026 MB perf.data ]
  $ perf inject -i perf.data --vm-time-correlation="dry-run 123"
  $ perf inject -i perf.data --vm-time-correlation="dry-run 123:456"
  Failed to parse VM Time Correlation options
  0x620 [0x98]: failed to process type: 70 [Invalid argument]
  $

 After:

  $ perf inject -i perf.data --vm-time-correlation="dry-run 123:456"
  $
