Update e2fsprogs to 1.43.6
Disable compilation of fuse2fs (we don't package it)
Disable thread support (only affects fuse2fs)
Enable linking with libblkid instead of using private (included) version.
The libblkid is ~210KBytes in size, but with using the shared library
the binaries are ~25KBytes smaller. This also brings it in sync with
most other Linux distributions.
