[PATCH] RISC-V: testsuite: fix target selector for sync_char_short

[Edwin Lu]

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.

gcc/testsuite/ChangeLog:

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