nss: Fix warnings generated by getcwd
getcwd() conforms to POSIX.1-2001 which leaves the behaviour when the
buf argument is NULL, undefined. This makes gcc 10+ throw the following
warning:
argument 1 is null but the corresponding size argument 2 value is 4096
Initially, this was fixed by disabling NSS_ENABLE_WERROR. This patch
re-enables NSS_ENABLE_WERROR (by leaving it to its default value) and
takes advantage of the existing functionality in nss that wraps the
getcwd call into a function making sure that the buf argument is always
properly allocated.
