If a read-only sstate mirror is used in conjunction with hash equiv,
then OSError will be raised when an sstate-cache hit is achieved.
This is because sstate_task_postfunc will try to "touch" the symlinks
that point to the read-only sstate mirror when sstate_report_unihash
has changed SSTATE_PKG.
This commit adds an additional exception handler to silently mask read
only rootfs errors thrown during the touch.
The fix is also duplicated to sstate_eventhandler as the code is very
similar but it may not be needed there.
Example of the error:

0001:
