9d69bc19b9 virhostuptime: Introduce virHostBootTimeInit()
The idea is to offer callers an init function that they can call
independently to ensure that the global variables get
initialized.

1b0de07f41 virhostuptime: Wrap virHostGetBootTimeProcfs() call in an ifdef
The virHostGetBootTimeProcfs() function is defined only for Linux
and therefore it's only call should also be done if we're on
Linux.

070d6969fe virhostuptime: Add linux stub for musl
When we want to know the boot timestamp of the host, we can call
virHostGetBootTime(). Under the hood, it uses getutxid() which is
defined by POSIX and properly check for in configure. However,
musl took a path where it declares the function but instead of
providing any useful implementation it returns NULL meaning "no
record found". If that's the case, use our second best option -
/proc/uptime and a bit of maths.
