Revert "also use DESTDIR in makefile.m{ingw,svc}"

This reverts commit 1655e63.

As of @karel-m [1]

"I am not sure whether DESTDIR concept make sense for MS Windows
paths. For example: `make -f makefile.mingw DESTDIR=c:\builddir\
PREFIX=c:\installdir` means that `"$(DESTDIR)$(PREFIX)\bin"` will
expand to `"c:\builddir\c:\installdir\bin"` which is obviously
invalid.
I propose reverting `also use DESTDIR in makefile.m{ingw,svc}`."
