usertools/devbind: support all VFIO no-IOMMU sysfs values

This patch adds support for 'y' and 'Y' values when reading vfio-pci unsafe_noiommu_mode flag. Possible values were taken from linux kernel (sysfs__read_bool() in tools/lib/api/fs/fs.c) Signed-off-by: Rogelio Domínguez Hernández <[email protected]> Reviewed-by: Robin Jarry <[email protected]>
