Remove third_party/eu-strip.

No longer required. It was originally added to support Android builds in
https://pdfium.googlesource.com/pdfium/+/450fbeaa, but
https://crrev.com/627463 moved it to buildtools/ in Chromium. So PDFium
now uses the buildtools/ copy, and no longer needs the copy in
third_party/.
