Enable RVV if qemu is detected

- include a fix for jpeg unittests to do at least 1 iteration
- include a fix for scale uv to only use linearup2 if filter is linear

Tested on qemu with Intel host:
[ RUN      ] LibYUVBaseTest.TestCpuHas
Cpu Flags 805306369
Has RISCV 268435456
Has RVV 536870912
Has RVVZVFH 0
Has X86 0
