fix derivation of UL-64QAM support from the UE Capabilities in the eNB 

Before this PR, the eNB was not activating UL-64QAM if the UE release was below 12,
due to an erroneous convertion of the ASN1 EUTRA Capabilities struct into the flattened
srslte::ue_capabilities_t.

With this PR, the eNB activates UL-64QAM for the following cases:
- UE category 5
- UE category 8 and release >= 10
- UE category UL 8 and release >= 12
