Fix Windows daemon: move 'all' target before LevelDB in makefile.mingw

The 'all: trianglesd.exe' target was defined after 'leveldb/libleveldb.a:'
making LevelDB the default target. Make would only build LevelDB and exit.
Move 'all' to before LevelDB so it becomes the default target (like
makefile.unix). Also pass explicit 'all' target in CI as belt-and-suspenders.
