[ELF] Don't shrink RelrSection Fixes PR43214. The size of SHT_RELR may oscillate between 2 numbers (see D53003 for a similar --pack-dyn-relocs=android issue). This can happen if the shrink of SHT_RELR causes it to take more words to encode relocation offsets (this can happen with thunks or segments with overlapping p_offset ranges), and the expansion of SHT_RELR causes it to take fewer words to encode relocation offsets. To avoid the issue, add padding 1s to the end of the relocation section if its size would decrease. Trailing 1s do not decode to more relocations.
