ptp: add testptp mask test

Add option to test timestamp event queue mask manipulation in testptp.

Option -F allows the user to specify a single channel that will be
applied on the mask filter via IOCTL.

The test program will maintain the file open until user input is
received.

This allows checking the effect of the IOCTL in debugfs.

eg:

Console 1:
```
Channel 12 exclusively enabled. Check on debugfs.
Press any key to continue
```

Console 2:
```
