dynamic_debug: add trim_prefix() to provide source-root relative paths
trim_prefix(path) skips past the absolute source path root, and
returns the pointer to the relative path from there. It is used to
shorten the displayed path in $DBGMT/dynamic_debug/control via
ddebug_proc_show(), and in ddebug_change() to allow relative filenames
to be used in applied queries. For example:
~# echo file kernel/freezer.c +p > $DBGMT/dynamic_debug/control
kernel/freezer.c:128 [freezer]cancel_freezing p " clean up: %s\012"
trim_prefix(path) insures common prefix before trimming it, so
out-of-tree module paths are shown as full absolute paths.
