[COMMITTED][testsuite] Fix vect-nop-move.c test (PR87763)

[Wilco Dijkstra]

Fix a failing test - changes in Combine mean the test now fails
eventhough the generated code is the same.  Given there are several
AArch64-specific tests for vec-select, remove the scanning of Combine
output.  Committed as trivial fix.
