[OE-core] [PATCH 4/4] sudo: improve reproducibility

[Juro Bystricky]

Delete various build host references from the internally
generated file sudo_usage.h. The references get compiled into
executables, which leads to non-reproducible builds.
The removed references (configure options) were only used as part
of the sudo "usage", and even then only when ran as root.
