[Buildroot] [PATCH 1/1] package/netsniff-ng: Allow to build with uclibc but w/o mausezahn

[Vadim Kochan]

mausezahn can't be build with uclibc because uclibc
does not provide ceill() function, so it does not allow
to build all netsniff-ng's tools with uclibc.

Fix it by moving mausezahn under separate config option,
which has own dependencies and packages selection (libnet & libcli).
