Aarch64: Better termination checks for sigcontext reading

When reading the reserved section in the sigcontext ensure the
address is updated on an unknown section. Also add additional
checks to prevent reading past the end of the array.

Fixes gdb.base/savedregs.exp

* aarch64-linux-tdep.c (AARCH64_SIGCONTEXT_RESERVED_SIZE): New
define.
(aarch64_linux_sigframe_init): Extra boundary checks.
