Add missing use statements in uimage handler (fixes error on use)
Add missing use statements in uimage handler.
Fixes this error:
$ strip-nondeterminism -T 123123123 Linux-1001.uImage
strip-nondeterminism: Linux-1001.uImage: Undefined subroutine
&Archive::Zip::computeCRC32 called at
/usr/share/perl5/File/StripNondeterminism/handlers/uimage.pm line 50.
Error shows up when trying to use strip-nondeterminism script, but does not show up in "make test" during build.
Also, add missing use statements in bflt handler.
