base-files: increase default system log size to 128 kB

Increase the default system log buffer size option
in /etc/config/system from 64 kB to 128 kB.

64 kB is barely enough for the boot items of a modern router
with a few add-on packages, but any subsequent logging will
quickly cause the early boot items to get overwritten in the
round-robin log buffer. Double the buffer size to 128 kB.

(Note: built-in default in ubox logd itself is still 16 kB)
