Jason Wessel 8f76fcd902 perf machine: Do not require /lib/modules/* on a guest 
For some types of work loads and special guest environments, you might
have a kernel that has no kernel modules.  The perf kvm record tool
fails instantiate vmlinux maps when the kernel modules directory cannot
be opened, even though the kallsyms has been properly processed.  This
leads to a perf kvm report that has no guest symbols resolved.

This patch changes the failure to locate kernel modules to be non-fatal.
