Remove cancellation support for syscall generation

This patch removes the cancellation mark from the auto-generation syscall
script.  Now all the cancellable syscalls are done throught C code using
the SYSCALL_CANCEL macro.  It simplifies the assembly required to each
architecture port, since the SYSCALL_CANCEL uses the already defined
INLINE_SYSCALL macros, and allows a more straigh fix on cancellation
machanism (since no more specific assembly fixes will be required).

Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.A
Also with build-many-glibc.py with remaning touched architectures.
