[PATCH] Speedup pass on macOS and brew

[pass-maillinglist at artursterz.de]

As there were no more complaints, I guess my patch is ok? I will tag it [PATCH] and hope, that it will go upstream.

Part 1:
Use three assumed default paths for gnu-getopt lookup

brew --prefix gnu-getopt will allways make some git lookups which may take
longer, depending on your internet connectivity. We therefore first look
in some default location for gnu-getopt. If it is not found there, make
the regular lookup.

Part 2:
Speed up the brew-based gnu-getop lookup

If gnu-getopt is not installed in the brew default path,
brew --prefix gnu-getopt will be used, which is annoyingly slow.
brew --prefix is way faster and should be prefered.

Part 3:
Infer gnu-getopt path using MacPorts

Unlike using brew, the MacPorts default path is assumed when infering the path to gnu-getopts.
This should not be done, since it is possible to install MacPorts and the ports in
non-standard paths.

Part 4:
Notify the user if getopt is not installed

In the past commits we implemented a new way to find gnu-getopt on macOS.
If we can not find it, pass can not be used, thus the user should be
notified about this.
