Bug#1131349: scipy: armhf FTBFS: linalg TestDTypes.test_det[g] fails

scipy 1.17.1 introduced linalg dtype tests in PR #24507

TestDTypes.test_det[g] (and test_det[G]) is failing on 32-bit armhf (arm-linux-gnueabihf).

A failing build log can be found at https://buildd.debian.org/status/fetch.php?pkg=scipy&arch=armhf&ver=1.17.1-1exp1&stamp=1773509541&raw=0

The workaround is to just skip test_det[g] and test_det[G] on armhf.

Reproducing Code Example:

python3 -c "import scipy.linalg; scipy.linalg.test(extra_argv=['-k', 'test_det[g] or test_det[G]', '-v'])"
