build: check for fopencookie() in configure
fopencookie(3) is a non-standard GNU extension and some libc implementations might not provide it (e.g. musl). Check for fopencookie in the configure script and disable building curvetun in case the function is not available, as curvetun is the only tool using fopencookie. Fixes #174 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
