[PULL 10/21] scripts/qemugdb: coroutine: Fix '--detailed' description

[Kevin Wolf <kwolf@redhat.com>]

From: Andrey Drobyshev <andrey.drobyshev@virtuozzo.com>

Both commands claim the coredump is copied before its registers get
patched, but patch_regs() writes to the coredump itself.  Describe what
actually happens, so that nobody expects their coredump to be left alone.
Fix a typo in "runing" while at it.

Fixes: 42f3c143c3a0 ("scripts/qemugdb: coroutine: Add option for obtaining detailed trace in coredump")
