Copying device name into a fixed-length buffer is problematic as
the name can be longer than the buffer, resulting in subsequent fields
getting corrupted and potentially even worse things.
Drop strcpy of device name and use of the copied value as it is known
anyway.
Before this fix:
/dev/mapper/owrt--volumes--e093cc66-rw_test: UUID="c66-rw_test" LABEL="test" VERSION="1.14" TYPE="f2fs"
After this fix:

The recent introduction of blkid_new_probe() and blkid_free_probe() in the
dynamically linked libblkid-tiny caused the dlopen'd libblkid.so to call into
the wrong version of blkid_new_probe() within blkid_new_probe_from_filename(),
leading to memory corruption and eventual segmentation faults.
Fixes: b82c5c1 ("libblkid-tiny: add functions for allocating & freeing probe struct")

This adds blkid_new_probe() and blkid_free_probe() which have to be used
in place of simple struct memory allocation. They will allow extending
probe struct by any extra initialization code and resources release.
Newly introduced probe.c file is based on original libblkid's code.

In the full liblkid there is no tag called "NAME" and the name value reported
by libblkid-tiny was just the kind of uuid passed to blkid_probe_set_uuid_as().
Strip any handling of this property to allow removing it from libblkid-tiny.

Attempt to dlopen() libblkid.so at runtime and use it for proping
filesystems if available.

Add an abstraction layer which separates block.c from libblkid-tiny implementation
details in order to prepare support for optionally using the full libblkid.
