PR 194 - Print path for AT_FDCWD

[Renaud Métrich]

Dear strace developers,

I would like to propose an enhancement consisting in printing the 
current working directory when having syscalls with AT_FDCWD parameter, 
this would be enabled when -y is used.

This feature would be very appreciated when digging into an strace where 
the program makes heavy use of relative paths, which makes it a big pain 
to get the path names.

See https://github.com/strace/strace/pull/194 for details.

Note that 2 CI items are currently failing, they look like as 
false-positive to me.

Thanks,

Renaud.
