PrmPkg: Set DXE_RUNTIME_DRIVER section alignment

Since PRM modules are DXE_RUNTIME_DRIVER images, this change sets
the linker flags to the expected section alignment values for
runtime code images. This serves as an example for platforms but
also results in PRM sample modules in the package having correct
section alignment.
