Backport of #17857.
The first argument in bin_PROGRAMS (bitcoind) was being silently dropped and never passed into the check-security.py or check-symbols.py scripts.
This has been the case since the scripts were added to the makefile in https://github.com/bitcoin/bitcoin/commit/f3d3eaf78eb51238d799d8f20a585550d1567719.
Example of the behavior:
# touch a, touch b, touch c
# python3 args.py < a b c
import sys
if __name__ == '__main__':
print(sys.argv)
# ['args.py', 'b', 'c']
# if you add some lines to "a",
# you'll see them here..
for line in sys.stdin:
print(line)
