package/cutelyst: fix linking with -latomic

Build is broken since commit 7333207eaf2900076185cba6641c6406d61c235e
because upstream overrides CMAKE_EXE_LINKER_FLAGS when building with
jemalloc:
https://github.com/cutelyst/cutelyst/commit/7d73eba273be365f15f1ffcb3d3ee7f1d44e10fb

+Subject: [PATCH] server/CMakeLists.txt: don't override CMAKE_EXE_LINKER_FLAGS
+
+Don't override CMAKE_EXE_LINKER_FLAGS as this could break the build if
+CMAKE_EXE_LINKER_FLAGS is already set by the user (for example to pass
+-latomic)
