openbsd_pkg: Fix KeyError (#3336) (#3407)
If package installation has an error after the package is install (e.g.
when running tags), then there will be output on stderr and the fallback
regex will match; however, since pkg_add exited non-zero, changed is
never added as a key to the dictionary. As a result the code at the end
of main that checks if anything has changed raises a KeyError.

(cherry picked from commit 02d0e3d286)

- Manage packages on OpenBSD using the pkg tools.
requirements:
- python >= 2.5
options:
name:
description:
- A name or a list of names of the packages.
required: yes
type: list
elements: str
state:
description:
- C(present) will make sure the package is installed.
C(latest) will make sure the latest version of the package is installed.
C(absent) will make sure the specified package is not installed.
choices: [ absent, latest, present, installed, removed ]
default: present
type: str
build:
description:
- Build the package from source instead of downloading and installing
a binary. Requires that the port source tree is already installed.
Automatically builds and installs the 'sqlports' package, if it is
not already installed.
- Mutually exclusive with I(snapshot).
type: bool
default: no
snapshot:
description:
- Force C(%c) and C(%m) to expand to C(snapshots), even on a release kernel.
- Mutually exclusive with I(build).
type: bool
default: no
version_added: 1.3.0
ports_dir:
description:
- When used in combination with the C(build) option, allows overriding
the default ports source directory.
default: /usr/ports
type: path
clean:
description:
- When updating or removing packages, delete the extra configuration
file(s) in the old packages which are annotated with @extra in
the packaging-list.
type: bool
default: no
quick:
description:
- Replace or delete packages quickly; do not bother with checksums
before removing normal files.
type: bool
default: no
notes:
- When used with a `loop:` each package will be processed individually,
it is much more efficient to pass the list directly to the `name` option.
