[klibc] dash: jobs: Replace some uses of fmtstr with stpcpy/stpncpy

[ dash commit 15a60c2357f772ccf953772859e8f9fc124442e2 ]

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.
