update-all: use common infrastructure

Update 'update-all.go' to use 'common.FileSystem' to get the path to the
'git-bundle-server' executable, and use 'cmd.CommandExecutor' to call
'git-bundle-server update'. The use of the common structures eliminate some
duplicate code as well as set up the command to be unit testable in the
future.
