  Tested x86_64-linux. Pushed to trunk.

This assertion fails for cris-elf where sizeof(datetime) is only 7, due
to lower alignment requirements. The assertion was used while I was
writing the code to check that the objects were as compact as I wanted,
but it doesn't need to be kept now.

libstdc++-v3/ChangeLog:

	* src/c++20/tzdb.cc: Remove static_assert.
