support/scripts/check-host-rpath: split condition on two statements

Inside the check_elf_has_rpath(), we check if the host binary has a
correct RPATH, which should be either an absolute path to
$(HOST_DIR)/lib, or a relative path using $ORIGIN. Those two
conditions are checked in a single statements, but as we are going to
add a third condition, let's split this up a bit:

 - If we have a RPATH to $(HOST_DIR)/lib -> we're good, return 0
 - If we have a RPATH to $ORIGIN/../lib -> we're good, return 0
 - Otherwise, we will exit the loop, and return 1
