wafsamba: Adjust 'match' logic to override paths in config.check()

wafsamba: Adjust 'match' logic to override paths in config.check()

messages that match various parts of the configure check progress e.g.
 'Checking for library iconv'
 'Checking for iconv_open'
 'Checking for header iconv.h'

are intercepted and the some path(s) modified with the associated option
value

    o buildtools/wafsamba/samba_conftests.py: Add arg_list variable
       arg_list contains the argument object returned from
       'argparser.ArgumentParser.add_argument' which is called
       with the content of the 'match' keyword passed to 'add_option'
       stripped out. The content of the 'match' keyword is saved as
       an attribute to the arg object appended to arg_list.
    o buildtools/wafsamba/samba_waf18.py:
       search arg_list (see above) that match and 'msg' argument passed
       to arg_list (allowing the dest variable associated with the argument
       to be accessed and added to some 'path' used during the 'check' phase
