What this PR does / why we need it:

We have a lot of failures for CentOS 4.18.x kernels. It seems that the image selector defaults them to GCC 8. I bumped them up to the GCC 9 image, and now it works locally. For example:

_output/bin/driverkit docker --output-module _output/scwx_centos_4.18.0-490.el8.x86_64_1.ko --kernelrelease 4.18.0-490.el8.x86_64 --kernelversion 1 --driverversion 4.0.0+driver --target centos --moduledevicename scwx-falco --moduledrivername scwx-falco --kernelurls http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/kernel-devel-4.18.0-490.el8.x86_64.rpm --builderimage docker.io/falcosecurity/driverkit-builder:any-x86_64_gcc10.0.0_gcc9.0.0-246e90f

^ works now :)

Which issue(s) this PR fixes:

Fixes # N/A

Special notes for your reviewer:

I only adjusted this in the CentOS builder, unsure this is universally true for all 4.18.x kernels. Also the change may be working because using GCC 9 bumps the builder image up to the GCC 9 image, which is based on bullseye rather than buster. Buster's build image has older versions of cpio/rpm2cpio, which had lower limits on how big rpms could be to unpack. Bullseye's version of these packages for managing rpms allows for bigger rpm file sizes.

Either way, the builds work now haha.

Does this PR introduce a user-facing change?:

Not really.

NONE
