patch 9.2.0210: tests: Test_xxd tests are failing

Commit: https://github.com/vim/vim/commit/076404ae41c61c7a34ee56a12c9d2dc0c059e959

patch 9.2.0210: tests: Test_xxd tests are failing

Problem: tests: Test_xxd tests are failing, after changing the xxd
manpage (after v9.2.0205)
Solution: Update the manpage, shorten the date and update the example,
regenerate the expected test output, skip the first 30 bytes
for the one of the xxd tests (Muraoka Taro)

Some of the Test_xxd tests depend on the contents of xxd.1. The patch
9.2.0205 changed xxd.1, but the test fixes were insufficient. The test
that dumps the beginning of xxd.1 and the test that reads 13 bytes
starting from byte 0x33 from the beginning were failing.

closes: #19763
