[PATCH 1/2] qemu/osdep: fix current process fds path for other OSes

[Clément Léger]

While Linux and Solaris uses /proc/self/fd, other OSes (MacOS,
FreeBSD) uses /dev/fd. In order to support theses OSes, use /dev/fd as
a fallback.

Fixes: 4ec5ebea078e ("qemu/osdep: Move close_all_open_fds() to oslib-posix")
