ash: jobs: Replace some uses of fmtstr with stpcpy/stpncpy

jobs: Replace some uses of fmtstr with stpcpy/stpncpy
Some uses of fmtstr, particularly the ones without a format string,
can be replaced with stpcpy or stpncpy. This patch does that so
we don't have to introduce unnecessary format strings in order to
silence compiler warnings.
