[PyQt] Make --qsci-api really optional

[Matteo Bertini]

Hello,

I've found that there is almost no way to explicitly exclude the 
qsci-api installation.

If one provide no option, but configure.py finds a default dir (quite 
common under linux) it tries to install apis there.

I suggest to activate the install in the default dir only if --qsci-api 
is provided. (patch follow)
