afalg: Use eventfd2 syscall instead of eventfd
The eventfd syscall is deprecated and is not available on aarch64, causing
build to fail:
engines/e_afalg.c: In function 'eventfd':
engines/e_afalg.c:108:20: error: '__NR_eventfd' undeclared (first use in this function)
return syscall(__NR_eventfd, n);
^
Instead, switch to the newer eventfd2 syscall, which is supposed to be
supported by all architectures.
This kind of issues would be avoided by simply using the eventfd(2)
wrapper from the libc, but there must be subtle reasons not to...
Tested on a aarch64 system running OpenSUSE Leap 42.1 (gcc118 from
https://cfarm.tetaneutral.net/machines/list/ ) and also cross-compiling
for aarch64 with LEDE (kernel 4.9).
This properly fixes #1685.
