ci: Make sure to always clear meson-install checkout dir

We currently remove the directory at the end of the script, but
that code is only reached when all previous operations were
successful.

Address this by first using an absolute directory path in /tmp
instead of a "random" location based on the CWD, then set a trap
to remove it on exit.
