build: rename dependency variable

Per [1], the naming convention for dependencies is '<project_name>_dep',
for consistency when importing the project as a meson subproject.
Rename the variable here to match this convention.

Based on [2] there appears to not be any current users of this as a
subproject which would need to be updated.

For now both autotools and meson will be maintained side by side.
Eventually we should remove the autotools build system.

utility/timer: Implement oneshot timers

This change is meant to enable users of the old openbmc timer class to
trivially use the timer if they only want single executions. It also
makes setting up the timer less verbose if you do not already know the
timeout interval.

Tested:
Run through unit tests and did a sample integration with
phosphor-watchdog and phosphor-networkd. Verified that the new
oneshot example works as expected.
