[Buildroot] [PATCH] package/fakeroot: use TCP for msg passing

[Matt Weber]

fakeroot can be built to either use SYSV IPC or TCP for message passing.

Cases for which the SYSV IPC version fails or causes problems but for
which fakeroot-tcp has been observed to work well include the items
listed below.

  * Multithreaded applications (using pthread)
  * Running under realtime-preempt kernel
  * Microsoft Windows 10 Services for Linux

I can't find a good reason to not make this the new default in the
Buildroot host build of fakeroot.  vs auto detecting which to build
depending on what the host env can support.

For good measure, in-addition to this change, I will submit an upstream
patch for the suggested configure.as update (pending a little cleanup
in that proposed patch). https://bugs.busybox.net/attachment.cgi?id=7791
