src/Makefile.am: Don't make 'install' depend on 'all'.

This fixes the issue where installing will re-generate
the voices and may sometimes fail setting up the
shadow directories in the espeak-data folder.

+install:
 	cd src && make DESTDIR=$(DESTDIR) PREFIX=$(PREFIX) BINDIR=$(BINDIR) INCDIR=$(INCDIR) LIBDIR=$(LIBDIR) install && cd ..
 	install -m 755 src/espeakedit $(DESTDIR)$(BINDIR)
