meson: Fix build with -Dtest_coverage=true

As can be seen in commit 8a62a1592ae00eab4eb153c02661e56b9d8d9032 (from
autoconf era), the coverage flags have to be used also when linking
objects. However, this was not reflected when we switched to meson.

Without this patch linking fails with undefined references to various
__gcov_* symbols.
