kmodule_linux: add ProbeOpts.IgnoreProcMods parameter
kmodule_linux: add ProbeOpts.IgnoreProcMods parameter

Unconditionally parsing /proc/modules for preloaded (and subsequently
skipped) kernel modules breaks use-cases where DryRunCB is used for
kernel module dependency gathering.
Add a new ProbeOpts.IgnoreProcMods parameter, which allows the caller to
explicitly disable this behaviour.
