package/sqlite: fix configure options for readline/editline support

The autosetup script will skip checking for readline.h when cross-compiling,
which will cause line-editing support for the sqlite3 shell to always be "none".

In this case, if the --editline option is provided, an error will be reported:
ERROR: Explicit --editline failed to find a matching library.

However, we can enable readline or editline support by specifying the CFLAGS
and LDFLAGS values ​​instead of having it handled automatically by the
autosetup configure script.

In addition, the libedit package actually depends on the ncurses package,
just like the readline package. So when using the libedit package,
also add the ncurses dependency.
