Fix meson setup failure not exiting build script when it should

[ABUCKY0]

Fixes #3

Given the following block of code:

COMPILE_STD_OUTPUT=$(mktemp)
echo "::group::Build Project"
meson setup --cross-file scripts/v5.ini build | tee $COMPILE_STD_OUTPUT
meson_exit_code=${PIPESTATUS[0]}
echo "PIPESTATUS: ${PIPESTATUS[@]}"
echo "Meson setup exit code: $meson_exit_code"
if [ $meson_exit_code -ne 0 ]; then
echo "Meson setup failed. Please check the logs for more information."
if [ "$INPUT_WRITE_JOB_SUMMARY" == "true" ]; then
{
echo "Meson setup failed. Please check the logs for more information. "
echo "***"
echo "

echo "::endgroup::"
this line

echo "PIPESTATUS: ${PIPESTATUS[@]}" was for some reason causing setup failures to not actually exit the build.sh script when they should

Fixes

• Remove this line
• Add tests to prevent this in the future
