Hadrian: profiling and debug enabled ways support -eventlog too

Previously, the following wouldn't work:

$ cat foo.hs
main = putStrLn "hello"

$ _build/stage1/bin/ghc -prof foo.hs -o foo && ./foo +RTS -p -l

Specifically, the RTS would complain about the -l flag. Trying to run ./foo with +RTS -l would complain that this required building the program with -eventlog or -debug. That's not the case with GHCs built with Make.

This patch emits -eventlog more often, when the way contains one of the following "way units": logging, debug or profiling. I'm planning to make a "proper" fix that makes the RTS itself aware of the -prof => -eventlog implication, just like it does for -debug => -eventlog, but that will be for another MR.
