Describe the bug

When iterating builds with the build container (not as sudo), the BPF ELF generated is owned by root, so successive builds fail until the ELF is manually removed e.g. via sudo

Steps to reproduce the bug

$ ./mybee build examples/tcpconnect/tcpconnect.c tcpconnect
Error: open examples/tcpconnect/tcpconnect.o: permission denied
2022/01/11 16:51:00 exiting: open examples/tcpconnect/tcpconnect.o: permission denied

 ls -al examples/tcpconnect/tcpconnect.o 
-rw-r--r-- 1 root root 731424 Jan 11 02:17 examples/tcpconnect/tcpconnect.o

Expected Behavior

UX allowing iteration without manual cleanup necessary
