t/Makefile: make "check-meson" work with Dash

The "check-meson" target uses process substitution to check whether
extracted contents from "meson.build" match expected contents. Process
substitution is unportable though and thus the target will fail when
using for example Dash.

Fix this by writing data into a temporary directory.
