ANDROID: arm64: Place CFI jump table sections in .text

Browse Source 
After the switch to non-canonical CFI jump tables, the jump table
sections were placed after the .text section. Merge these sections
into .text to fix issues with error injection and kallsyms.

[nathan: This change is necessary in android-4.19 to boot after upstream
         LLVM commit 7b346357db30 ("[ELF] Orphan placement: prefer the
         last similar section when its rank <= orphan's rank"), which
         changes how sections not described in linker scripts are laid
         out in the final binary]
