Description

Luatest crushes with an error due to luarocks cannot find 'tarantool' module. The error looks like this:

/usr/bin/lua5.1: ...ocks/share/tarantool/rocks/luatest/scm-1/bin/luatest:3: module 'tarantool' not found:No LuaRocks module found for tarantool
	no field package.preload['tarantool']

How to reproduce

To reproduce it is necessary to have tarantool and lua5.1 in the same dir (/usr/bin/ for example). There is a tt rocks configuration:

$ ./tt rocks
Configuration:
   Lua:
      Version    : 5.1
      LUA        : /usr/local/bin/tarantool (ok)
      LUA_INCDIR : /usr/local/include/tarantool (ok)
      LUA_LIBDIR : (ok)

   Configuration files:
      System  : /etc/luarocks/config-5.1.lua (not found)
      User    : /home/milchenko/src/tt/.rocks/config-5.1.lua (not found)

   Rocks trees in use:
      /home/milchenko/src/tt/.rocks ("user")
      /usr/local ("system")

Using this we can get following error:

$ ./tt rocks install luatest
$ .rocks/bin/luatest PATH_TO_DIR
/usr/bin/lua5.1: ...ocks/share/tarantool/rocks/luatest/scm-1/bin/luatest:3: module 'tarantool' not found:No LuaRocks module found for tarantool
...

Expected behavior

It is expected that luatest will find 'tarantool' module and will run tests according provided path to dir.
