package/gawk: renumber remaining patch

Commit aaba432e2cae (package/gawk: drop incorrect patch) was sent on the
list before e6942ad11ff0 (package/gawk: fix double free during kernel
build) was applied. But when aaba432e2cae was eventually applied, the
remaining patch was not renumbered.

Fix that now.
