GH/scripts/environment.sh: add -o pipefail

Try to set -o pipefail. The option should be supported since POSIX v8
(2024). Of course it is supported by shells like bash/zsh long time ago
but it was added to dash [here], which is merged to dash 5.13, so it
is not in any Ubuntu version yet. So adding '|| true' to suppress
omission.

XIMEA URL extraction must have been updated 'sed -e "... q"' causes
broken pipe, which becomes now fatal.
