tc: add bash-completion function
Add function for command completion for tc in bash, and update Makefile
to install it under /usr/share/bash-completion/completions/.
Inside iproute2 repository, the completion code is in a new
`bash-completion` toplevel directory.
v2: Remove `if` statement in Makefile: do not try to install in
/etc/bash_completion.d/ if /usr/share/bash-completion/completions/
is not found; instead, the user can override the installation path
with the specific environment variable.

# 1. Check if previous word is a global option; if so, propose arguments.

# 2. Check if current word is a global option; if so, propose completion.

# there is one, first call _tc_direct_complete to see if previous word is

# waiting for a particular completion. If so, propose completion and exit.

# (add|delete|show|...).

# 5. Propose completion based on main and sub- command in use. Additional

# functions may be called for qdiscs, classes or filter options.
