ARM: decompressor: Include .data.rel.ro.local 



The .data.rel.ro.local section has the same semantics as .data.rel.ro
here, so include it in the .rodata section of the decompressor.
Additionally since the .printk_index section isn't usable outside of
the core kernel, discard it in the decompressor. Avoids these warnings:

arm-linux-gnueabi-ld: warning: orphan section `.data.rel.ro.local' from `arch/arm/boot/compressed/fdt_rw.o' being placed in section `.data.rel.ro.local'
arm-linux-gnueabi-ld: warning: orphan section `.printk_index' from `arch/arm/boot/compressed/fdt_rw.o' being placed in section `.printk_index'
