a87e4788d2 util: virdaemon: fix waiting for child processes
Unlike `waitpid`, `virProcessWait` only returns -1 (error) or 0
(success), so comparing that to `pid` will always be false and the
parent will report failure with:

error : main:851 : Failed to fork as daemon: No such file or directory

even though the grandchild process is succesfully running. Note that the
errno message is misleading: it was last set when trying to find a
restart state file.

c360ea28dc util: virdaemon: fix compilation on mingw
The daemons are not supported on Win32 and therefore were not compiled
in that platform. However, with the daemon code sharing, all the code in
utils *is* compiled and it failed because `waitpid`, `fork`, and
`setsid` are not available. So, as before, let's not build them on
Win32 and make the code more portable by using existing vir* wrappers.

fc5925f1e0 util: introduce shared daemon startup code
Several daemons have similar code around general daemon startup code.
Let's move it into a file and share it among them.
