tools/mtd-utils: update to 1.4.5

Browse source 
This updates mtd-utils in tools:
100-optional_lzo.patch and 101-ubifs-optional_lzo.patch
are now uneeded as a WITHOUT_LZO flag is provided by the
upstream sources. All remaining patches are refreshed
for the new version.
135-mkubifs_optional_lzo.patch was created to respect
WITHOUT_LZO also in mkubifs.

Signed-off-by: Daniel Golle <dgolle@allnet.de>
