python3-checksec-py, python3-pylddwrap, python3-icontract: add recipes

they were sent for meta-security long time ago in 2021:
https://lists.yoctoproject.org/g/yocto/message/54470
but never merged there, now there are lief, docopt, rich, asttokens
already in meta-python and checksec-py depends on lief version, e.g.
976d530867
is needed to fixcompatibility with newer lief currently in meta-python

+Subject: [PATCH] main: Add option to ignore symlinks
+
+When analyzing a complete rootfs (which might not be the rootfs of the
+analyzing system) symlinks within that rootfs might be broken. In
+particular absolute symlinks. However, if by chance such a symlink
+currently points to a valid binary in your system, this binary pointed
+to is analyzed. This commit adds the possibility to ignore symlinks to
+files (symlinks to dirs are already ignored by default). This allows to
+solve the issue described above, and if the whole rootfs is analyzed
+there shouldn't be a loss of information (because all the binaries will
+be analyzed anyway). Additionally, this also saves some time when
+performing the analysis.
+
