drop unused libmsc/meas_feed.h

Change I0d57ac214e574e267fa9752daf76566197b9aa64 forgot to remove this
file along with meas_feed.c.

Note also the weirdness: that patch removes the proper
include/osmocom/msc/meas_feed.h, but there's also this other one.

This libmsc/meas_feed.h always existed from the start as an unused
orphan, see: 

https://git.osmocom.org/osmo-bsc/diff/openbsc/src/libmsc/Makefile.am?id=b4771a6871efb3cf12b371aedc575912984ca528

No need to drop from Makefile.am, since it is already gone from there.

(meas_feed from the old osmo-nitb (openbsc.git) has / should have moved to
osmo-bsc. There are no measurement reports in the MSC. Refer to osmo-bsc.git
instead from now on.)
