Remove lowest buffer size from the list of options.
This buffer may not be big enough to prevent us from losing tracepoints
with the file_write_period used by Traceur (which is 2500).
Even low-end devices should be fine using a bigger buffer, which is
preferable to having a more frequent write period.
If a user previously had their buffer size set to 4096, that size will
remain their setting upon upgrading Traceur until they change it.
