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.
