[lldb] Fix minidebuginfo-set-and-hit-breakpoint.test

This was failing for me because of this error:
llvm-objcopy: error: 'build/tools/lldb/test/ObjectFile/ELF/Output/minidebuginfo-set-and-hit-breakpoint.test.tmp.mini_debuginfo': section '.dynsym' cannot be removed because it is referenced by the section '.hash'

Patch by Konrad Kleine!
