priv dir must be on PATH in order to use sqlite-erlang

[pmahoney]

In order to use sqlite-erlang, the priv dir containing the sqlite-port executable must be on the PATH environment variable. The following patch solves the problem (I hope the formatting comes out correctly...).

Edit: unfortunately, this only seems to work when sqlite is in ERL_LIBS environment variable or an absolute path is given to -pa. code:priv_dir/1 doesn't work with relative paths specified like -pa ebin.
