build: default to not trying to build epoll on non-Linux systems

dbus/dbus-pollable-set-epoll.c currently errors out if __linux__ is not
defined.  Allows passing -Depoll=enabled to override.

Based on patch by Jonathan Perkin for pkgsrc on illumos:
https://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/dbus/patches/patch-meson.build?rev=1.2
but modified to only change default of 'auto' and check for all non-Linux OSes.
