When using a domain login, `whoami` returns the login in user\domain format. This leads to either warnings on unrecognised escape sequences or escaped characters being generated for the user. This patch ensures that any backslash is escaped to a double-backslash to make sure the name is preserved correctly. This patch does not enforce escaping on the KBUILD_BUILD_USER variable, as this is something the user has control of and can escape if required.
