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.
