[Tarantool-patches] [PATCH v2 luajit 3/5] test: adjust lua-Harness test suite for Tarantool

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

This patch makes it possible to run lua-Harness test suite using
Tarantool.

203-lexico.t and 301-basic.t is adjusted to valid working with
out-of-source build in Tarantool CI.

Inside Tarantool's GitHub-CI there is no defined variable LOGNAME nor
USERNAME. This leads to test failure inside CI, because a string is
expected. So, now USERNAME is set manually via CMake.
