inconsistency in gdb/mi -file-list-exec-source-files

[Xavier de Gaye <xdegaye at gmail dot com>]

The output of '-file-list-exec-source-files' differs between gdb 7.2 and
gdb previous releases: with gdb 7.2 the 'fullname' attribute becomes the
file basename and the 'file' attribute becomes the full pathname. It was
the reverse previously.
