MXS-2732 Rename sqlite-src-3110100 to sqlite-src-3110100.old

Browse Source 
Originally, the sqlite installation was imported into the MaxScale
repository in the one gigantic MaxScale 1.4 -> 2.0 commit.

Consequently, there is no import commit to compare to if you want
to extract all MaxScale specific changes. To make it simpler in the
future, sqlite will now be imported in a commit of its own.
