linux: Inline __syscall_internal_cancel and __syscall_cancelazanella/cancel-wrappers-inline
It improves some interception tools such as valgrind, however on
multithread the __syscall_cancel_arch is called.
The result libc.so has a slight larger code size:

It mimics internally how cancellable entrypoints were implemented
before 89b53077d2a58f00e7debdfe58afabe953dac60d, where cancellation
handlign were done inline in the syscall wraper.
