[PATCH v2] kernel-devsrc: Check for gen_vdso_offsets.sh before copying on riscv

[PATCH v2] kernel-devsrc: Check for gen_vdso_offsets.sh before copying on riscv

[Khem Raj]

This file is introduced in newer kernels >= 5.15 but some RISCV machines
still use 5.13 kernels, this ensures that kernel-devsrc can build on
older kernels for RISCV
