ARM: unwind: modules: Fix the mismatch between .ARM.exidx* and .text

This commit modifies the module linker script for ARM to merge
.ARM.extab.text.* and .ARM.exidx.text.* sections. It addresses a stack
unwinding failure caused by newer compilers splitting sections.

[Severity: Low]
This isn't a bug, but there appears to be an extra hyphen in the wildcard
pattern between z and A. Could this be corrected to match the [0-9a-zA-Z_]*
pattern used in the .text section just above?
