Since kernel 5.17+ the mips asm.h includes isa-rev.h, which itself was
added 4.17. Without it, lzma-loader will fail to build:
make[3] -C target/linux compile
make[5]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.
In file included from head.S:22:

compilation terminated.

ERROR: target/linux failed to build.
So add the file to the files to install. We can do that unconditionally,
since the oldest supported kernel 5.15 already includes it, even it if
does not need it.
