Directories are entries with uncompressed size zero and ending with
character '/' or '\' are allowed in apks since b/204425803. These
entries should not be considered for alignment since they are not
mmap by the framework.

Problem: Zipalign operates over several false assumptions. First it
assumes that zip entries are in the same order in the body and in
the Central Direcotry. Second, it assumes there are not space
between entries. This makes alignment incorrect when these asserts
are not true.
Solution: Don't align entries by tracking bias based on input zip
entry location. Calculate the expected alignment based on the out-
put zip file and correct with extra padding.

Use zip_archive directly. Note that this codepath is used only
when recompressing archives with zopfli during the alignment step.
It's unclear whether this is in use at all, but I verified that the
results are identical (note the usage of the "-z" flag in the test
below).
Test: make && out/host/linux-x86/bin/zipalign -v -f -z 8 \
