    RISC-V: testsuite: fix target selector for sync_char_short
    
    The effective-target selector for riscv on sync_char_short did not
    check to see if atomics were enabled. As a result, these test cases were
    ran on targets without the a extension. Add additional checks for zalrsc
    or zabha extensions.

            * lib/target-supports.exp: Fix effective target sync_char_short
            for riscv*-*-*
