base-files: stage2: improve /proc/*/stat parser
Simply reading /proc/*/stat as a space-separated string will not work as the process name may itself contain spaces. Hence we must match on the '(' and ')' characters around the process name and can then handle the remaining string as space-separated values. This fixes shell error messages which have been popping up the console due to spaces in process names being interpreted as field separators. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
