Fix an uninitialized variable access error.
To reproduce, one could write:
foo = files('foo.c')
foo[0].path()
and get:
Traceback (most recent call last):
[snip]
File "/home/trhd/Projects/meson/mesonbuild/interpreterbase.py", line 398, in method_call
raise InvalidArguments('Variable "%s" is not callable.' % object_name)
UnboundLocalError: local variable 'object_name' referenced before assignment
Fix this by handling file objects separately.
