pacsift: no output if --sysroot=/ is specified explicitely

[AladW]

Example:

$ xargs -a <(printf -- '--satisfies=%s\n' aurutils-git) pacsift --sysroot=/ <&-
# empty output
$ xargs -a <(printf -- '--satisfies=%s\n' aurutils-git) pacsift <&-
local/aurutils-git
alad-base/aurutils-git

Note that I'm using xargs -a here, because I want to be able to pass many --satisfies=foo to pacsift without exceeding ARG_MAX. I know of no other way to use --satisfies with values taken from stdin.

It's specifically when using --sysroot and <&-. <&- closes the file descriptor, freeing up fd 0, parsing the config then opens the sysroot directory and gets fd 0, then when pacsift goes to check stdin for packages it sees the directory fd which is not a tty so it tries to read a list of packages, but of course there are none.

This should be fixed on the yolo branch. Can you double check that it works for you?

I can confirm it works with latest master. Thanks!
