Fix memory leaks in 'vix' tools plugin.
* vix plugin retrieves the power script file paths from the
config file but doesn't free them and this causes a memory leak.
Fixed the code to free the filepaths.
* In GuestAuthPasswordAuthenticateImpersonate function, the VGAuth
handle is not freed when the impersonation fails. Fixed the
code to call VGAuth_UserHandleFree in the error path.
Note: I executed one guest operation with wrong credentials.
Every failure leaks 75 bytes of memory. (in Centos 64-bit VM)
* Fixed another minor issue in the code. At couple of places in
the code, replaced 'err' with 'vgErr' for storing the return value
of VGAuth_UserHandleAccessToken.
