package/ipsec-tools: disable for musl toolchains

__P() is used for compatibility with old K&R C compilers. With
ANSI C this macro has no effect.

Unlike for util-linux and ipkg packages where it was easy to remove
each __P() macro, ipsec-tools use it all over the tree and require a
"big" patch to enable musl support.

Since upstream seems not verry active (last release 2014-02-27)

So, disable ipsec-tools with musl based toolchains.

This fixes a compilation error with musl libc because of undeclared
__P.

While at it, reorder "depends on" and "select" lines in Config.in
