Update the hw config when "-skindir" is configured

If the "-skindir" is configured, the start-up process won't use
avdInfo_getSkinHardwareIni() to read the "hardware.ini" file
which is specified by the argument of "-skindir". And the
arguments in the specified "hardware.ini" won't be used.
This patch can solve the problem.
