kernel-devsrc: restore compatibility with kernel < v4.10

Browse Source 
The kernel commit that added the syscall table generation tools
for ARM platform (ARM: convert to generated system call tables)
wasn't merged until kernel release v4.10.

Current assumption in kernel-devsrc recipe is that these syscall
scripts exist, which breaks the build for external board layers that are
still using 4.9.x kernels:

  cp: cannot stat ‘arch/arm/tools/syscall*’: No such file or directory

so only try to install the scripts when they actually exist.

(From OE-Core rev: 7b4d77d7f909c0ae27553fd9c480f069f12e468f)
