ci: Load KVM kernel module for LAVA runners

Browse Source 
If 'HWCI_KVM' enviroment variable is set, load the KVM kernel module
specific to the detected CPU virtualisation extensions: vmx for Intel
VT and svm for AMD-V.

As an additional optimization, handle HWCI_KERNEL_MODULES probing in the
main shell process instead of creating an unnecessary subshell.
