FindMPI: make sure computed link flags are not de-duplicated
In commit f7eaa342de (FindMPI: Store imported target link flags as a
list instead of a string, 2019-06-14, v3.15.0-rc2~2^2) we used
`separate_arguments` to parse the extracted link flags and add them to
`INTERFACE_LINK_LIBRARIES`. That property is not meant for link flags
and CMake may de-duplicate them. This is particularly problematic for
flags like `-Wl,-rpath -Wl,/path1 -Wl,-rpath -Wl,/path2`.
In commit 39c572c9c9 (FindMPI: Updated to use INTERFACE_LINK_OPTIONS,
2019-06-24) we moved the parsed flags over to `INTERFACE_LINK_OPTIONS`,
but that may still perform de-duplication. Avoid the parsing and
de-duplication of flags by passing the original string via `SHELL:`
instead.
Fixes: #19516
