doc: Avoid some overfull lines in the TeX output.

* doc/glibc-functions/futimesat.texi: Replace a long @code with a
@example.
* doc/pastposix-functions/pthread_attr_getstackaddr.texi: Insert a
newline before the long URL.
* doc/pastposix-functions/pthread_attr_setstackaddr.texi: Likewise.
* doc/relocatable-maint.texi: Use @smallexample instead of @example.
Add line breaks in code snippets.
