fix qtmain's .prl file not being used

at some point we stopped adding the qtmain's library path before its
respective -l flag, which lead to qmake being unable to resolve the
library location and thus ignoring its prl file.

untangle use of system vs. shell path(-list) semantics

"system" refers to the system's native shell, which is what qmake's
system() invokes, and whose convention by far most commands invoked from
a makefile will need.
"shell" refers to the shell invoked by make, which diverges from the
system shell only when qmake/mingw32-make is called from an msys shell.
its conventions need to be used for anything the shell itself does
(e.g., assembling env variables, but also command line argument
unquoting) and the commands the mkspec sets according to the shell
(e.g., QMAKE_MOVE).

make QMAKE_DIRLIST_SEP consistent with QMAKE_DIR_SEP

that is, make it match the shell used by the make command.

this is unlike DIRLIST_SEPARATOR and DIR_SEPARATOR, which always match
the actual system shell.
