Wrong open mode for file descriptor 4 in utils/nfc-relay-picc.c

[GoogleCodeExporter]

The open mode for fdopen of file descriptor 4 in nfc-relay-picc utility should 
be "w", not "r". Otherwise the utility fails when it tries to write into this 
descriptor.

Note: this affects when the utility is run in initiator mode only.

See attached patch.
