codec cosmetic: move old FR ECU code to ecu_fr_old.c

The current FR codec ECU implementation consists of two parts:
there is a pair of functions that implement the actual functionality,
and these functions are also made public as a now-deprecated legacy
API - and there is the new ECU abstraction.  If the FR ECU
implementation behind the generic ECU abstraction is to be changed
to a different one, the old implementation still has to be retained
for those public legacy osmo_ecu_fr_reset() and osmo_ecu_fr_conceal()
API functions to remain available and unbroken.  Move this legacy
ECU implementation to its own C module in preparation for changing
the preferred ECU implementation.
