tests/modules/performance/byte-compile-lua: improve bytecode detection

Browse source 
Previously, to determine if a file is byte-compiled, a simple binary
file detection was used, specifically checking if it contained any null
bytes. This commit updates the check to read the file header and compare
it with a known LuaJIT header.
