fstrim: add --all to discard all filesystem
* read /proc/self/mountinfo to get filesystems
* ignore net and pseudo filesystems
* ignore unaccessible filesystems (over mounted by another FS)
* read disk sysfs queue/discard_granularity to detect is discard support
* call FITRIM ioctl
* silently ignore EOPNOTSUPP (for example LUKS without discard) and ENOTTY
(for example vfat) errors
