Add support for zipped LLVM profile files.

This change is a follow-up to a recent change which allowed LLVM raw profile files
to be directly used with blaze.  This change allows zipped LLVM raw profile
files.

This uses //tools/zip:zipper to extract the zipped file contents.

This also adds a new option to //tools/zip:zipper, 'j', to junk directories while
unzipping.

Tested:
  blaze test //devtools/blaze/integration:fdo_test
  blaze test //third_party/ijar/test:zip_test

RELNOTES[NEW]: Zipped LLVM profiles are now supported.
