perf tools: Remove dependency on libnewt
Now that the map browser shares the input routine with the hists browser, there is no need for using any libnewt routine, so remove all traces except for honouring NO_NEWT=1 on the makefile command line as an indication that TUI support is not needed, in fact it just sets NO_SLANG=1.
