sqlite3: make cli-editing support selectable

sqlite3 can use libedit, readline or disable command-line editing
support altogether. This commit adds a choice to menuselect.

The default is changed from readline to libedit, as the latter is
upstream's first choice and is also a bit smaller than readline.
