The asm/ and asm-generic/ namespaces are implementation details of the UAPI
headers and not meant for direct usage.

Use the equivalent headers from the linux/ namespace instead.

While at it also drop the duplicate include of linux/signal.h from sys.h.

- Link to v1: https://lore.kernel.org/r/20250305-nolibc-asm-headers-v1-1-f2053def2ee7@linutronix.de
