mkcompile_h: git rid of UTS_TRUNCATE from LINUX_COMPILE_{BY,HOST}
UTS_VERSION is set to struct uts_namespace, hence a too long string should be truncated so it fits in 64 characters. On the other hand, LINUX_COMPILE_BY/HOST are not set to uts_namespace. They are just used in the banners, which do not have specific length limitation. I dug into the git history, but I could not find the reason why these two strings must fit in 64 characters. Remove them. Now that UTS_VERSION is the only user of UTS_TRUNCATE, I squashed it. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
