on_exit is not portable

[joerg-krause]

Since commit 4a160b1 wavemon uses on_exit(), which is not portable and not available on the C libraries musl and uClibc. According to the Linux kernel man page : Portable application should avoid this function, and use the standard atexit(3) instead.

Thank you for keeping an eye on portability. Will fix this as soon as possible.
