lib/common.mk: support eBPF programs in nested directories

The current build system sets the name of the generated skeleton directly to the file's name minus the .skel.h suffix. In case the eBPF program was in a nested directory, this leads to syntax errors in the skeleton file. This commit support ebpf programs in nested directory by poping out the directory part in the eBPF program name without breaking the build of currently available eBPF program.
