defconfig: msm8226: enable options for QView

Make Kprobes built-in, as it's needed by QView and
other tools. Build in cpaccess, because it does not
work as a module with the latest module protection
scheme.

When not in use, enabling these options does not produce
any statistically significant overhead.
