staging: Strip files in sysroot
Add functionality to strip binaries/libraries going into the sysroot. Whilst this does fractionally slow down the build, it also significantly reduces the size of the sstate cache files. (From OE-Core rev: 30f3774f4cd5bbb8c1e6884aeff5af91ab053fc1) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
