package/mtd-utils: update to 1.4.5

This updates packages/utils/mtd-utils and includes all patches from
tools/mtd-utils, so the two may eventually be merged.
I also added 150-fix_ubi-utils_static.patch which is a hack needed
to include libcrc32.o in the static binaries.
Having them static makes sense as only ubiformat is required on the target.

[juhosg:
- add build-time dependency on util-linux
- allow to specify dependency for each subpackage
- update ubifs optional lzo patch
- add more patches]
