970d6d2096 ELF: Have __rela_iplt_{start,end} surround .rela.iplt with --pack-dyn-relocs=android. 
In #86751 we moved the IRELATIVE relocations to .rela.plt when
--pack-dyn-relocs=android was enabled but we neglected to also move
the __rela_iplt_{start,end} symbols. As a result, static binaries
linked with this flag were unable to find their IRELATIVE relocations.
Fix it by having the symbols surround the correct section.
