test: Fix any2ppm on MSVC

C99 initialization is not allowed.

Error macros are used even in the non-daemon version, hence errno.h
should always be included.

Fixes:

any2ppm.c(107) : error C2065: 'EINTR' : undeclared identifier
any2ppm.c(107) : error C2051: case expression not constant
any2ppm.c(108) : error C2065: 'EAGAIN' : undeclared identifier
any2ppm.c(108) : error C2051: case expression not constant
any2ppm.c(271) : error C2059: syntax error : '.'
