[Buildroot] [PATCH 2/6] package/crda: replace pycrypto by pycryptodomex

[Romain Naour <romain.naour@gmail.com>]

From [1]:
"PyCryptodome is a fork of PyCrypto, which is not maintained any more
(the last release dates back to 2013 [2]). It exposes almost the same
API, but there are a few incompatibilities [3]."

[2] https://pypi.org/project/pycrypto/#history
[3] https://pycryptodome.readthedocs.io/en/latest/src/vs_pycrypto.html

Update the patch 0001-crda-support-python-3-in-utils-key2pub.py.patch
since it add pycrypto.

From [4]
"CRDA is no longer needed as of kernel v4.15 since commit 007f6c5e6eb45
("cfg80211: support loading regulatory database as firmware file") added
support to use the kernel's firmware request API which looks for the
firmware on /lib/firmware. Because of this CRDA is legacy software for
older kernels. It will continue to be maintained."

 Subject: [PATCH] crda: support python 3 in utils/key2pub.py
 
 utils/key2pub.py can now be run under either python 2.7 or python 3.x.
 This required some minor syntactical changes as well as switching from
-M2Crypto to pycrypto, since M2Crypto doesn't support python 3.x.
+M2Crypto to pycryptodomex, since M2Crypto doesn't support python 3.x.
 
 In addition, some errors in the generated source file keys-ssl.h are
 fixed:
