AIX,HP-UX: Fix RPATH handling when CMP0065 is set to NEW
The CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGS setting has always been meant
for flags needed to export symbols from executables for use by shared
library plugins. Since commit v3.4.0-rc1~58^2~1 (CMP0065: Restrict the
use of CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGS, 2015-08-24) this is made
explicit by using the flags only for executables with ENABLE_EXPORTS,
guarded by CMP0065 for compatibility.
On some platforms we were accidentally using this setting to pass other
flags to the linker:
* AIX: -bnoipath, -brtl
* HP-UX: +s, +nodefaultrpath
These flags are incorrectly dropped when CMP0065 is set to NEW. Fix
this by moving the flags to more appropriate places for linking
executables.
