Subject: lei: force --jobs=1,1 for SQLite < 3.8.3

SQLite prior to 3.8.3 did not reset its PRNG for generating
unique temporary file names, so it would barf on t/lei-up.t
occasionally due to O_EXCL -> EEXIST conflicts.

This fixes occasional test failures under CentOS 7.x which ships
SQLite 3.7.17.
