feat: Add support for environment variable read 
Add support (for Linux and Windows for now) for reading the
environment variables of a process, with a similar syntax to
os.Environ().
For Windows, this includes some refactoring for clean access to the
RTL_USER_PROCESS_PARAMETERS structure which points to the command
line and the environment variables.

065e609cbf Refactor "process" package 
* All context-less wrapping functions (the ones without WithContext
suffix) were moved into process.go since they all are the same.
* Call context is now passed to all underlying functions in
*WithContext() functions.
* All common *BSD bits were moved to process_bsd.go.
* Process.Tgid() method lacked a WithContext counterpart, so
Process.TgidWithContext() was added for uniformity.
* NewProcessWithContext() function was added since NewProcess() is
used a lot throughout the module, and there is no way to pass a
context to it.

This is a part of #761 effort.

8ff2ab3187 Add "vet" target to the Makefile 
Making the "vet" target will run "go vet ./..." for each supported
GOOS.

Also, some of the warnings produced by go 1.15 vet were mitigated.

the remaining usages to use the functions from x/sys/windows.

e5ca4477a1 [process][windows] WIP #586 use win32 API in process.Exe but fallback on WMI 
This method only lets a 32bit program get other 32bit processes exe path
and a 64bit program get other 64bit processes exe path, so we fallback to
the slow (but kind of reliable) WMI calls if we can't access to the other
process module.

6b539051d2 [process][windows] Use win32 API in process.Children() instead of slow WMI call 
The CreateToolhelp32Snapshot+Process32First+Process32Next combo already
iterates over all processes, so it would be inefficient to enumerate all
processes with process.Processes() and then calling p.Ppid() on each of
them: we just use this combo to get all processes and their ppid in a
single iteration.

This is faster by a factor of 25 compared to the previous WMI call.
