Subject: scripts: Drop shell sstate-cache-management

Since there is a faster python version, drop the slower shell one.

-Welcome to sstate cache management utilities.
-sstate-cache-management.sh <OPTION>
-
-Options:
-  -h, --help
-        Display this help and exit.
-
-  --cache-dir=<sstate cache dir>
-        Specify sstate cache directory, will use the environment
-        variable SSTATE_CACHE_DIR if it is not specified.
-
-  --extra-archs=<arch1>,<arch2>...<archn>
-        Specify list of architectures which should be tested, this list
-        will be extended with native arch, allarch and empty arch. The
-        script won't be trying to generate list of available archs from
-        AVAILTUNES in tune files.
-
-  --extra-layer=<layer1>,<layer2>...<layern>
-        Specify the layer which will be used for searching the archs,
-        it will search the meta and meta-* layers in the top dir by
-        default, and will search meta, meta-*, <layer1>, <layer2>,
-        ...<layern> when specified. Use "," as the separator.
-
-        This is useless for --stamps-dir or when --extra-archs is used.
-
-  -d, --remove-duplicated
-        Remove the duplicated sstate cache files of one package, only
-        the newest one will be kept. The duplicated sstate cache files
-        of one package must have the same arch, which means sstate cache
-        files with multiple archs are not considered duplicate.
-
-        Conflicts with --stamps-dir.
-
-  --stamps-dir=<dir1>,<dir2>...<dirn>
-        Specify the build directory's stamps directories, the sstate
-        cache file which IS USED by these build diretories will be KEPT,
-        other sstate cache files in cache-dir will be removed. Use ","
-        as the separator. For example:
-        --stamps-dir=build1/tmp/stamps,build2/tmp/stamps
-
-        Conflicts with --remove-duplicated.
-
-  -L, --follow-symlink
-        Remove both the symbol link and the destination file, default: no.
-
-  -y, --yes
-        Automatic yes to prompts; assume "yes" as answer to all prompts
-        and run non-interactively.
-
-  -v, --verbose
-        Explain what is being done.
-
-  -D, --debug
-        Show debug info, repeat for more debug info.
