GFRMx00: Remove OUI-based discovery and pairing

plugins/gfrm.c:
Change GFRMx00 IR discovery to use BD_ADDR type for determining whether
the newly discovered remote is GFRM100 or GFRM200. The BD_ADDR type is
the 7th byte read from /tmp/bd-addr-fifo. It is BDADDR_BREDR (0x0) for
GFRM100 and BDADDR_LE_PUBLIC (0x1) for GFRM200. This information is
provided by the FIFO writer (miniclient).

test/gfiber-agent:
Change GFRMx00 pairing to use GFRMx00 device name only. The device name
is always available since it is set by plugins/gfrm.c at discovery time.
