package/zerofree: new package

Browse Source 
zerofree is a utility which scans the free blocks in an ext2 filesystem
and fills any non-zero blocks with zeroes.

https://frippery.org/uml/

The ext2fs/ext2fs.h header guards the inclusion of <sys/types.h> behind
HAVE_SYS_TYPES_H, which is an autotools-defined macro that is only
supposed to be defined by the package itself, i.e. e2fsprogs, and that
should not leak into installed headers. However, e2fsprogs does leak it,
so we work it around, liek gentoo does.
