apps: Remove leading space in CMake linker directive variables.

While building the Xilinx R5 demo apps, the following error message
occurs:

CMake Error at apps/examples/echo/CMakeLists.txt:38 (add_executable):
Target "rpmsg-echo.out" links to item " -Wl,--defsym,_rsc_table=0x3ed20000
-T"/OpenAMP-Project/gh3/open-amp/apps/system/generic/machine/zynqmp_r5/
linker_remote.ld""
which has leading or trailing whitespace.  This is now an error according
to policy CMP0004.

Remove the leading space.
