Bug#1023938: findimagedupes: uninitialized value warnings when program is run

[Jonathan H N Chin]

Package: findimagedupes
Version: 2.20.1-1
Severity: normal

Dear Maintainer,

The debian build process appears to amend the Inline::C setup:

/usr/lib/x86_64-linux-gnu/perl5/5.36/findimagedupes/C.pm :
```
    use Inline
	C => 'DATA',
	NAME => 'findimagedupes::C',
	VERSION => '0.01',
	CCFLAGSEX => "$ENV{'CFLAGS'} $ENV{'CPPFLAGS'}",
	LDDLFLAGS => "$ENV{'LDFLAGS'}",
```

However, by default, these environment variables are not set,
resulting in warning messages when the program is run:

```
    Use of uninitialized value in concatenation (.) or string at /usr/lib/x86_64-linux-gnu/perl5/5.36/findimagedupes/C.pm line 5.
    Use of uninitialized value in concatenation (.) or string at /usr/lib/x86_64-linux-gnu/perl5/5.36/findimagedupes/C.pm line 5.
    Use of uninitialized value $ENV{"LDFLAGS"} in string at /usr/lib/x86_64-linux-gnu/perl5/5.36/findimagedupes/C.pm line 5.
```
