environment: '-C' doesn't throw when the NSS is dysfunctional.
Previously, if the name service switch was dysfunctional, as can happen
on foreign distros lacking nscd, "guix shell -C" would crash with a
backtrace on the uncaught 'getpwuid' exception. To address that, catch
the exception and deal with it gracefully.
Reported by remsd1 on #guix.
* guix/scripts/environment.scm (launch-environment/container): Wrap
'getpwuid' call in 'false-if-exception'.
