tests: Increase test timeout and honor ‘GUIX_TESTS_BUILD_TIMEOUT’.

Rigid build time limits let some unit tests fail on slow hardware.

Set default timeout to 5 minutes and make it configurable via
`GUIX_TESTS_BUILD_TIMEOUT` environment variable.

* guix/tests.scm (%tests-build-timeout): New variable.
(open-connection-for-tests, call-with-external-store): Use it.
* tests/guix-environment-container.sh, tests/guix-home.sh,
tests/guix-pack-localstatedir.sh, tests/guix-pack-relocatable.sh: Use it to
define ‘GUIX_BUILD_OPTIONS’.
