[ELF][test] Delete large temporary files and make some temporary files smaller with two text segments

Large files are cumbersome on some filesystems and can more easily trigger ENOSPC.

Some tests use two text sections with output section addresses to test branch ranges.
Use two text segments to prevent LLD from filling the gap and unnecessarily increasing the output size.

With this change, there is no test/ELF temporary file larger than 100MiB.
