Description of problem:
When trying to build simple-kmod on ARM you get:

error: build error: error determining starting point for build: no FROM statement found

It turns out the FROM line received a blank value for $IMAGE. In the SRO logs you see blank values for the kernels:

2022-03-21T09:21:30.094Z	INFO	[1;32msimple-kmod  [0m	Runtime Information	{"ClusterUpgradeInfo": {"4.18.0-305.34.2.el8_4.aarch64":{"OSVersion":"8.4","OSMajor":"rhel8","OSMajorMinor":"rhel8.4","clusterVersion":"4.10","driverToolkit":{"imageURL":"","kernelFullVersion":"","RTKernelFullVersion":"","OSVersion":""}}}}

This is because SRO is looking for a kernel that ends with _arm64, but the name of the architecture is aarch64:

# uname -a
Linux dtk 4.18.0-305.34.2.el8_4.aarch64 #1 SMP Mon Jan 17 09:23:59 EST 2022 aarch64 aarch64 aarch64 GNU/Linux

# rpm -qa |grep kernel
kernel-core-4.18.0-305.34.2.el8_4.aarch64


Version-Release number of selected component (if applicable):
4.10


Steps to Reproduce:
1. Install OCP 4.10 on ARM
2. Install NFD and SRO from OLM
3. Follow the steps to build simple-kmod with a configmap


Actual results:
The build pod fails to build the driver container image
