[XS] Change in libosmocore[master]: Remove sync() after writing VTY config

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/37798?usp=email ) Change subject: Remove sync() after writing VTY config ...................................................................... Remove sync() after writing VTY config Running sync() after writing VTY config causes the process to stop for a fraction of a second. This may result in delayed processing that causes buffer underruns, overflows and delay. This is a problem with applications that do real-time signal processing such as osmo-trx and osmo-bts. After some discussions, I decided to simply remove the sync() commands from the VTY's write function. There is still a backup file created of the previously saved configuration before writing the current configurtion. Loosing current configuration caused by a system crash afterwards is very unlikely with modern file systems.
