libdtrace: Do not set SHF_ALLOC on SUNW_dof relocation sections

Browse Source 
The section will contain static relocations which do not need to be
preserved after linking, and moreover these relocations may reference
symbols that end up getting removed.

Do not set SHF_ALLOC and instead let the linker decide what needs to be
done.
