Improve build portability by including asm-generic/errno.h, instead of
linux/errno.h.
The difference between these two headers can be summarized as following:
- asm-generic/errno.h contains generic error code definitions that are
intended to be common across different architectures,
- linux/errno.h includes architecture-specific error codes and
provides additional (or overrides) error code definitions based on
the specific architecture where the code is compiled.
Considering the architecture-independent nature of scx, the advantages
of being able to use architecture-specific error codes are marginal or
negligible (and we should probably discourage using them).
Moving towards asm-generic/errno.h, however, allows the removal of
cross-compilation dependencies (such as the gcc-multilib package in
Debian/Ubuntu) and improves the code portability across various
architectures and distributions.
This also allows to remove a symlink hack from the github workflow.
