(cmp_kernel_versions) move it from any.pm to common.pm; thus preventing lazy loading of syscall.ph through

any->detect_devices>modules>list_modules>MDK::Common>MDK::Common::System>syscall.ph

This can end in crashing mgaaplet when performing live update (mga#3042)
because of lazy loading of syscall (by which time perl may as well have been
updated including syscall.ph which leave eg perl/5.12.x for perl/5.14.x)

This also saves quite some memory for:
- net_applet (5Mb aka 11%),
- mgapplet (7Mb aka 14%)
(as well as maybe for drakxnet but that's more transient):
