gsm_08_58: add propritary IE to signal Repeated ACCH Capability

3GPP TS 24.008, section 10.5.1.7 specifies a Repeated ACCH Capability
bit in the Classmark 3 IE. Unfortunately, there is no way specified how
the Repeated ACCH feature should be controlled on RSL level. Since it is
not unusual that BTS/BSC vendors occassionally add propritary IEs to
different RSL messages we may pick this as a solition as well and add a
propritary RSL_IE_OSMO_REP_ACCH_CAP IE, so that we can enable repeated
FACCH/SACCH on the BTS side when we send RSL CHAN ACT or RSL CHAN MODE MODIFY
messages.
