Subject: tests: install resource files to datadir, not libexecdir

The .bmp / .hex / .txt / .dat / .wav files shipped alongside the test
binaries are not executables; they are read-only data. Installing them
under ${libexecdir}/installed-tests/SDL2/ is both inconsistent with the
GNOME installed-tests convention (data lives under ${datadir}, only
binaries under ${libexecdir}) and trips OpenWrt's package QA which
expects every regular file in /usr/libexec/ to carry the executable
bit. Move them to ${datadir}/installed-tests/SDL2/ alongside the
matching ${exe}.test descriptors, and pin the permissions to 0644 so
the umask of the build host cannot influence the installed mode.
