Bug Description
SRU Justification
Impact: The fix for bug 1852581 causes the build log to be spammed with "/bin/bash: line 5: warning: command substitution: ignored null byte in input" each time an unsigned module is processed.
Fix: Replace the fix with a different one which does not result in the message.
Test Case: Build with debug package build enabled, and check for the message in the logs. Also confirm that the resulting modules are signed, aside from those in staging and not whitelisted in drivers/
Regression Potential: I've tested the patch for the above criteria, and all is working as expected, so this should not result in any regressions.
