Remove the function EnableBlocklist() and add a constructor argument to
enable/disable the use of modules.blocklist. In all cases, the
enabling/disabling of the blocklist happens immediately after creating
the Modprobe object. So this simplies libmodprobe.
Additionally, the use of the blocklist by libmodprobe should be enabled
by default unless explicitly disabled during creation of the Modprobe
object. Currently, only modprobe(8) defaults to not using the blocklist
and includes the argument -b BLOCKLIST for enabling it. That
functionality remains.
This refactor allows us to use the blocklist during first stage init.
However, additional logic is needed to not return an error for the
blocked non-aliased modules during first stage init; otherwise, the
error would result in an init crash leading to a device reboot. So fixup
LoadListedModules() to allow blocking modules without returning an
error.

The first argument in a modules.dep line must end with a colon so fail
if that condition is not met.

In the short term this will be used to help implement support for
multiple kernel module directories but it may be useful in other
contexts as well.

If the blacklist is enabled, blacklisted modules are treated as though
they are not present.

Add a remove method which will unload a given module from the kernel,
along with any modules it depended on, assuming those modules are now
unused.

Modprobe functionality is required both within first stage init and also
as a standalone binary. Create a library for this using and extending
the logic in modalias_handler.cpp.
First stage init will attempt to load modules from /lib/modules.
