[lld][ELF] Fix gc-sections-print.s failure in read-only directories

[itf]

If ld.lld is invoked without the -o option, it defaults to writing its output to a.out in the current directory. This can cause 'Permission denied' errors if a test is executed in a directory without write permissions, as can happen in some build environments.

Add -o %t2 to this command, consistent with other commands in the same test file, to prevent this failure by ensuring ld.lld writes to a temporary file instead of a.out.
