guix: move *-check.py scripts under contrib/guix

These scripts are not meant for general developer usage. They are for
use on the release binaries, which have been compiled in an environment
that makes various assumptions in regards to c library, compiler
options, hardening options, patching etc.

-=================
-
-Perform basic security checks on a series of executables.
-
-symbol-check.py
-===============
-
-A script to check that release executables only contain
-certain symbols and are only linked against allowed libraries.
-
-For Linux this means checking for allowed gcc, glibc and libstdc++ version symbols.
-This makes sure they are still compatible with the minimum supported distribution versions.
-
-For macOS and Windows we check that the executables are only linked against libraries we allow.
-
-Example usage:
-
-    find ../path/to/executables -type f -executable | xargs python3 contrib/devtools/symbol-check.py
-
-If no errors occur the return value will be 0 and the output will be empty.
-
-If there are any errors the return value will be 1 and output like this will be printed:
-
-    .../64/test_bitcoin: symbol memcpy from unsupported version GLIBC_2.14
-    .../64/test_bitcoin: symbol __fdelt_chk from unsupported version GLIBC_2.15
-    .../64/test_bitcoin: symbol std::out_of_range::~out_of_range() from unsupported version GLIBCXX_3.4.15
