[PATCH] Add more missing parentheses to Python calls to print

[PATCH] Add more missing parentheses to Python calls to print

[Simon Marchi]

I noticed that there are calls to Python's print outside the gdb.python
directory, so this patch adds those that I found were missing.  They were
found by grepping for "python print [^(]", so it's always possible that
I missed some others that use another pattern.

Parentheses are mandatory with Python 3 when calling print.

gdb/testsuite/ChangeLog:

	* gdb.ada/py_range.exp: Add missing parentheses.
	* gdb.dwarf2/symtab-producer.exp: Same.
	* gdb.gdb/python-interrupts.exp: Same.
	* gdb.gdb/python-selftest.exp: Same.

This is pre-approved, but can you remove the space before
the opening parenthesis? Since "print" has become a function
in Python 3, and we try to follow the standard python style,
unlike our GNU Coding Style in C/C++, there should be no
space before the parenthesis.

Thank you!
