hurd: Also make it possible to call strlen very early

Browse Source 
strlen, which is another ifunc-selected function, is invoked during
early static executable startup if the argv arrives from the exec
server. Make it not crash.

Checked on x86_64-gnu: statically linked executables launched after the
exec server is up now start up successfully.
