net/NetConnections relies on lsof??

It looks like net/NetConnections relies on running the lsof executable.

The python version of psutil doesn't have this dependency.

Yes, python psutil reles on

• linux: proc filesystem
• freebsd: sysctl
• darwin: proc info
• windoes: GetExtendedTcpTable or else

It is hard to implement all different way. But from my research, almost every UNIX like system has lsof, so I just use it. I know there are better way like psutil, but I have no time currently.
PR is always welcome!

On Darwin it relies on execing ps to find process information.

lsof isn't installed by default on a lot of platforms. This causes issues for example on centos. One test is also looking for lsof in /usr/bin/lsof

--- FAIL: Test_Parent (0.00s)
    process_test.go:293: error fork/exec /usr/bin/lsof: no such file or directory

This fails even though lsof is installed in the standard path on centos which is /usr/sbin/lsof
