cros_workon: catch and show errors when eval-uating $(grep ^CROS_WORKON)
Running eval on code grep-ed from other files carries a risk of
errors. For instance, some .ebuild files can have CROS_WORKON*
variable definitions split across several lines, causing cryptic
"syntax error" messages. This code catches invalid grep-ed code before
it can have any side-effect, then displays it and its location as an
ERROR.
