[FHI72] Fix long PRACH format

The problem was that xran_is_prach_slot() compared if the current slot is the
scheduled one. However, this becomes irrelevant if long PRACH format used.
Successfully tested end-to-end the PRACH index 7 with TDD DDDDDDDSUU and Benetel
v2.0.5.

In addition, PRACH format 0 is also verified with FW v2.0.5. An example gNB config file can be found at [`gnb.sa.band77.273prb.fhi72.2x2-benetel550-long-prach.conf`](../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band77.273prb.fhi72.2x2-benetel550-long-prach.conf).
