We unfortunately cannot easily download these because of the file names (not
ending in patch) and patch format (p0), so convert to p1 format and include
in package/bash.

+Bug-Description:
+
+Bash-4.4 warns when discarding NUL bytes in command substitution output
+instead of silently dropping them.  This patch changes the warnings from
+one per NUL byte encountered to one warning per command substitution.
