add new package: pigz for parallel gzip compression

[Musicminion]

Description

This pr add a new cmd tool pigz, for parallel gzip compression. And I add this tool to spk/synocli-file because it seems more like a file tool.

Nowadays, most Synology NAS have multi-core processor (like j4125, v1500b...). When using tar gz, we can add pigz to perform parallel compression to improve speed.

Btw, this is my first attempt at packaging, please help me fix the bugs I don't know that I've created yet, much thanks~

@Musicminion thanks for this.
Can you please create a dedicated branch? You will get serious troubles using the master branch for PRs.

Otherwise it looks good to me.
We are used to create something like spksrc/diyspk/pigz for tools that are part of larger synocli-* packages.
This helps adding/updating tools, since it does not require to build all dependent tools.
With this you can even install a single tool as a package (when you have a local dev env).

@Musicminion some additional comments (after looking into the code)

The source does not provide a configure script, so it is ok to skip this step.
And the Makefile does not support an install target, so the custom install is required.

But you shouldn't need to modify the COMPILE_MAKE_OPTIONS variable as you did.
But I guess the Makefile should be patched to make the CC, CFLAGS and LDFLAGS variables optional and use the variables of the spksrc dev env.

So I propose to add

ADDITONAL_CFLAGS = -O3 -Wall -Wextra -Wno-unknown-pragmas -Wcast-qual

and to patch the Makefile like this:

 # LDFLAGS=-g -fsanitize=thread
 # CFLAGS=-O3 -Wall -Wextra -Wno-unknown-pragmas -Wcast-qual -g -fsanitize=address

BTW:
The install target does not need to install the man file(s) since there is no man command under DSM.
(and remove it in PLIST)
