[RISCV] Omit "@plt" in assembly output "call foo@plt" (#72467) 
R_RISCV_CALL/R_RISCV_CALL_PLT distinction is not necessary and
R_RISCV_CALL has been deprecated. Since https://reviews.llvm.org/D132530
`call foo` assembles to R_RISCV_CALL_PLT. The `@plt` suffix is not
useful and can be removed now (matching AArch64 and PowerPC).

GNU assembler assembles `call foo` to RISCV_CALL_PLT since 2022-09
(70f35d72ef04cd23771875c1661c9975044a749c).

Without this patch, unconditionally changing MO_CALL to MO_PLT could
create `jump .L1@plt, a0`, which is invalid in LLVM integrated assembler
and GNU assembler.

34b21e817f [RISCV] Use OS-specific stack-guard ABI for Fuchsia 
Fuchsia provides a slot relative to tp for the stack-guard value,
which is cheaper to materialize than the default GOT load.
