This patch produces GCC warnings about the use of memcpy().

This patch fixes it:
2019-07-19 Bruno Haible <br...@clisp.org>
areadlink-with-size, xgethostname, xgetdomainname: Fix GCC warning.

* lib/areadlinkat-with-size.c: Likewise.
* lib/xgethostname.c: Likewise.
* lib/xgetdomainname.c: Likewise.
