scripts/get_maintainer.pl: add --pattern-depth



--pattern-depth is used to control how many levels of directory traversal
should be performed to find maintainers.  default is 0 (all directory levels).

For instance:

MAINTAINERS currently has multiple M: and F: entries that match
net/netfilter/ipvs/ip_vs_app.c

IPVS
M:	Wensong Zhang <wensong@linux-vs.org>
M:	Simon Horman <horms@verge.net.au>
M:	Julian Anastasov <ja@ssi.bg>
[...]
F:	net/netfilter/ipvs/

NETFILTER/IPTABLES/IPCHAINS
[...]
M:	Patrick McHardy <kaber@trash.net>
[...]
F:	net/netfilter/

NETWORKING [GENERAL]
M:	"David S. Miller" <davem@davemloft.net>
[...]
F:	net/

THE REST
M:	Linus Torvalds <torvalds@linux-foundation.org>
[...]
F:	*/

Using this command will return all of those maintainers:
(except Linus unless --git-chief-maintainers is specified)

$ ./scripts/get_maintainer.pl --nogit -nol \
	-f net/netfilter/ipvs/ip_vs_app.c
Julian Anastasov <ja@ssi.bg>
Simon Horman <horms@verge.net.au>
Wensong Zhang <wensong@linux-vs.org>
Patrick McHardy <kaber@trash.net>
David S. Miller <davem@davemloft.net>

Adding --pattern-depth=1 will match at the deepest level
$ ./scripts/get_maintainer.pl --nogit -nol --pattern-depth=1 \
	-f net/netfilter/ipvs/ip_vs_app.c
Julian Anastasov <ja@ssi.bg>
Simon Horman <horms@verge.net.au>
Wensong Zhang <wensong@linux-vs.org>

Adding --pattern-depth=2 will match at the deepest level and 1 higher
$ ./scripts/get_maintainer.pl --nogit -nol --pattern-depth=2 \
	-f net/netfilter/ipvs/ip_vs_app.c
Julian Anastasov <ja@ssi.bg>
Simon Horman <horms@verge.net.au>
Wensong Zhang <wensong@linux-vs.org>
Patrick McHardy <kaber@trash.net>

and so on.
