Remove collate.linux.utf8.sql's assumptions about ".utf8" in locale names.
Tweak the test so that it does not depend on the platform using ".utf8" asthe extension signifying that a locale uses UTF8 encoding. For the mostpart this just requires using the abbreviated collation names "en_US" etc,though I had to work a bit harder on the collation creation tests.This opens the door to using the test on platforms that spell localesdifferently, for example ".utf-8" or ".UTF-8". Also, the test is nowsomewhat useful with server encodings other than UTF8; though depending onwhich encoding is selected, different subsets of it will fail for lack ofcharacter set support.
