build: add option to exclude executables/dirs from being stripped 



Sometimes it may be desirable to keep debug symbols for some binaries and
libraries on the target. This commit introduces the config option
BR2_STRIP_EXCLUDE_FILES, which is interpreted as a list of such binaries
and libraries, and the option BR2_STRIP_EXCLUDE_DIRS, which indicates
directories excluded from stripping entirely.
These exclusions are passed to the find command in the target-finalize step.
