Frontend: Don't append -target-min-inlining-target target to implicit module builds.

Browse Source 
When performing an implicit module build, the frontend was prepending
`-target-min-inlining-target target` to the command line. This was overriding
the implicit `-target-min-inlining-target min` argument that is implied when
`-library-level api` is specified. As a result, the wrong overload could be
picked when compiling the body of an inlinable function to SIL for emission
into the client, potentially resulting in crashes when the client of the module
is back deployed to an older OS.
