CMake: Avoid dsmyutil warnings on shared libraries using libjpeg 

We link object files with the same names into the BundledLibjpeg
static archive.

This caused warnings when running dsymutil on shared libraries using
that archive:
 skipping debug map object with duplicate name and timestamp
 could not find object file symbol for symbol _jpeg_start_compress

Avoid that by creating copies of the source files with different
names, so that all object files are unique.

Pick-to: 6.2 6.5 6.6 6.7
Fixes: QTBUG-123324
