[PATCH 2/4] kconfig: tests: Provide defconfig outfile for savedefconfig

[Nicolas Schier]

Let kconfig test framework's 'savedefconfig' forward the requested
output 'defconfig' filename to 'conf'.

The original implementation was calling 'conf' with '--savedefconfig'
but missed the mandatory filename for the defconfig output file.

While at it, honour the 'dot_config' argument which points to the input
config file.
