test_roc_driver.c runs timeout under riscv64

[gyx47]

description

In this pr ,I make the test roc_driver.c don't work under riscv64.it runs TIMEOUT under riscv64, but when I run the test with
meson test -C build --timeout-multiplier=120 --print-errorlogs, it turns out to be OK.

environment

• libsrtp-1-2.7.0-1

• Platform: RISC-V 64 bit

• log files:

libsrtp-12.7.0-1-riscv64-check.log

My operating environment is an riscv64 environment virtual machine of the arch architecture of Windows WSL.

reproduce

The process is as follows:

1. Obtain all dependencies libsrtp needed and compile it.
2. run meson test -C build --print-errorlogs

patch

For fewer downstream distributors,I suggest ignore the entire test suite.I add

#ifndef __riscv

#endif

to /test/roc_driver.c
