[Bug-gnulib] Add strdup.h.

[Simon Josefsson]

I get warnings when building with -ansi -pedantic, because there is no
prototype for strdup.  I imagine calling strdup without a prototype
might not work portably, because it would cast a 'char*' into 'int'
(function call) and back to 'char*' (assignment), but I'm not sure.
There is a warning though.
