sqlite: Enable optimization

Commit a28940d9d542f3d7f2a5f88c4f2701a1818cf153 changed the SQLite
build to use CFLAGS instead of NIX_CFLAGS_COMPILE, but that's really
bad because it clobbers the default -O2 flag. So all this time we had
an unoptimized SQLite build. (This is one of the reasons why
NIX_CFLAGS_COMPILE exists - messing with CFLAGS is almost never a good
idea.)
DBD::SQLite: Update to 1.44

haskell-yi-fuzzy-open: new package

According to @bennofs , this should now work regardless of what kind of
mess the user is in.
