gsm_08_08: add missing GSM0808_SCT_EXT

As per 3GPP TS 48.008, section 3.2.2.103, the "Codec Type" field may
contain either a certain 3GPP Speech Codec Type directly (4 bit value),
or the so called "Codec Extension" = 0xFh, in which case the real Codec
Type follows in the next octet as "Extended Codec Type".

CSD is such an example, the encoding is defined as follows:

     8    7    6    5    4    3    2    1
  +----+----+----+----+-------------------+
  | -- | PI | PT | -- |        0xFh       |
  +----+----+----+----+-------------------+
  |      Extended Codec Type (CSData)     |
  +----+----+-----------------------------+
  | R2 | R3 |                             |
  +----+----+-----------------------------+

  CSData is coded with 0xFDh or '1111 1101' (0xfd).

We already have GSM0808_SCT_CSD, add the missing GSM0808_SCT_EXT.
