Replace extract-srcjars.sh with zipsync tool

extract_srcjars.sh uses zipinfo and unzip, which fail with an
error on an empty zip file.  Instead of trying to hack around
this (which is hard to make guarantees for since they are
non-hermetic host tools), replace them with a go tool to unzip
a set of zip files into a directory.
