common: Use default_errsource for call-gpg and exectool.

Browse source 
* common/call-gpg.c (my_error_from_syserror, my_error_from_errno): New.
Use these wrappers.
* common/exectool.c (my_error_from_syserror): New.  Use these
wrappers.
--

Function in common should use the error source of the component which
links them.  The global variable DEFAULT_ERRSOURCE is set early by
each component to make this possible.
