fio: Generalize zonemode=zbd

Generalize the implementation of the zbd zonemode for non-linux systems
and Linux systems without the blkzoned.h header file (that is, linux
systems with a kernel predating v4.10 or kernels compiled without zoned
block device support).

The configuration option CONFIG_HAS_BLKZONED determines if the system
supports or not zoned block devices. This option can be set for Linux
only for now. If it is set, the file oslib/linux-blkzoned.c is compiled
and the 3 functions defined are used by the zbd.c code to determine a
block device zoned model, get zone information and reset zones.
For systems that do not set the CONFIG_HAS_BLKZONED option,
zonemode=zbd will be useable with regular block devices with the
zbd code emulating zones as is already done currently.
