meson: Fix -latomic check
Commit 54ba73ef102f (configure.ac/meson.build: Fix -latomic test) fixed
some checks for -latomic, and then commit 54bbe600ec26 (configure.ac:
rework -latomic check) further extended the fixes in configure.ac but
not in Meson. This commit extends those fixes to the Meson tests.
Fixes: 54bbe600ec26 (configure.ac: rework -latomic check)
