Use current kernel version as default if not specified
...
When a BPF program doesn't specify the target kernel version, the
most compatible option is to set the program kernel version to match
the currently running kernel.

fix: make maps compatible with kernel <= 4.14
...
In kernel 4.15 and additional parameter was added to allow maps to have
names but using this breaks on older kernels.
This change makes it so the name is only added on kernels 4.15 and
newer.
