[PATCH 2/3] rm_work.bbclass: handle stamp files while doing rm_work

[Dongxiao Xu <dongxiao.xu@intel.com>]

From: Dongxiao Xu <dongxiao.xu@intel.com>

If rm_work is scheduled, we need to remove the stamps of fetch, unpack,
patch, etc, while just leaving the setscene varients.

For example, we'd task stamps like:

xxx-1.4.7-r3.do_compile
xxx-1.4.7-r3.do_configure
xxx-1.4.7-r3.do_fetch
xxx-1.4.7-r3.do_generate_toolchain_file
xxx-1.4.7-r3.do_install
xxx-1.4.7-r3.do_package.emenlow
xxx-1.4.7-r3.do_package_write
xxx-1.4.7-r3.do_package_write_ipk
xxx-1.4.7-r3.do_package_write_rpm
xxx-1.4.7-r3.do_patch
xxx-1.4.7-r3.do_populate_sysroot.emenlow
xxx-1.4.7-r3.do_setscene
xxx-1.4.7-r3.do_unpack

and after rm_work, we have stamps of:

xxx-1.4.7-r3.do_package_setscene.emenlow
xxx-1.4.7-r3.do_package_write_ipk_setscene
xxx-1.4.7-r3.do_package_write_rpm_setscene
xxx-1.4.7-r3.do_populate_sysroot_setscene.emenlow

This can solve the issue we meet if we force to schedule a task after
contents in ${WORKDIR} are removed.

Also this can solve the rm_work issue we met after machine specific
sysroot is implemented.

Thanks for Richard's suggestion to tracking these issues down.
