[Tarantool-patches] [PATCH v2 luajit 14/30] test: adapt activeline check in the PUC Lua test

[Sergey Kaplun]

LuaJIT does not report line with single "end" statement
(the last line of the function) as an active line in
debug.getinfo(), unlike Lua does. There is no bytecode
related to this line, so it is "unreachable" and
may be considered not active.

This patch excludes the last line of a function from the check,
considering LuaJIT's behaviour.
