package/fakeroot: test for SYSV IPC support

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

A bug was discovered where Microsoft Windows 10 Services for Linux
doesn't include support for SYSV IPC MsgQ.  This patch adds support to
detect this case and automatically build fakeroot to use the TCP
transport instead (It is assumed a TCP transport would definitely have
more overhead then MsgQs so the default wasn't changed to TCP).
