software/ors-amarisoft: enb.jinja2.cfg: Unify logging

1. Currently we have separate log_options for LTE and NR cases with listing
different subsystems in each. But in MultiRU one enb will be driving both LTE
and NR cells at the same time, so we will need to define both LTE- and
NR-related levels.

-> Merge all log settings into one log_options as a preparatory step

For current state it does not hurt for an LTE if we set e.g. ngap.level, and it
does not hurt for NR if we set e.g. s1ap.level - since those layers will be
unused. This way merging log settings for both LTE and NR subsystems is ok.

--------

2. Factorize log_phy_debug handling: instead of duplicating whole
log_options line and changing only phy.level settings there, construct the
log_options line programmatically and handle phy.level on its own.

--------

3. Use log/enb.log log_filename for both LTE and NR cases. In the upcoming
MultiRU there might be several cells activated at the same time and in general
it will be not possible to say are we doing "enb" or "gnb" now - for example if
there will be two cells - one LTE and one NR.

-> Use enb.log for log filename uniformly similarly to how the software is
named (lteenb) even though it can work as both enb and gnb.

For the reference we do the same with enb.xlog in nexedi/slapos!1522 .
