edge: Extend gprs_rlcmac_dl_tbf::handle by egprs_ms_class

The multislot (MS) class and the EGPRS MS class can also be passed
via BSSGP in an MS Radio Access Capability element which can
optionally be contained in a DL-UNITDATA PDU. While this case is fully
supported for GPRS, the EGPRS MS class in BSSGP messages is ignored.

This commit extends gprs_rlcmac_dl_tbf::handle to pass the EGPRS MS
class, too.

Note, that the EGPRS class is not yet taken from the CSN.1 RA
capability and is always set to 0. Note also, that append_data
still uses ms_class only.
