Add support for a vendor directory and libeconf (#136)

With this, it is possible for Linux distributors to store their
supplied default configuration files somewhere below /usr, while
/etc only contains the changes made by the user. The new option
--enable-vendordir defines where Linux-PAM should additional look
for pam.d/*, login.defs and securetty if this files are not in /etc.
libeconf is a key/value configuration file reading library, which
handles the split of configuration files in different locations
and merges them transparently for the application.
