samples: cellular: modem_shell: Disable CONFIG_LOG_RUNTIME_FILTERING

CONFIG_LOG_RUNTIME_FILTERING is enabled by default whenever
CONFIG_SHELL is enabled. However, this is not really useful unless
CONFIG_LOG_CMDS is enabled, or log_filter_set() is used at run-time.
While this is done to make sample.cellular.modem_shell_modem_uart_trace
configuration from sample.yaml to fit into FLASH for thingy91,
all configurations benefit from this by ~5.5kB of FLASH.
