security/clamav: update to 0.102.2

Update clamav to 0.102.2.

## 0.102.2

ClamAV 0.102.2 is a bug patch release to address the following issues.

- [CVE-2020-3123](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-3123):
  An Denial-of-Service (DoS) condition may occur when using the optional credit
  card data-loss-prevention (DLP) feature. Improper bounds checking of an
  unsigned variable resulted in an out-of-bounds read which causes a crash.

- Significantly improved scan speed of PDF files on Windows.

- Re-applied a fix to alleviate file access issues when scanning RAR files in
  downstream projects that use libclamav where the scanning engine is operating
  in a low-privelege process. This bug was originally fixed in 0.101.2 and the
  fix was mistakenly omitted from 0.102.0.

- Fixed an issue wherein freshclam failed to update if the database version
  downloaded is 1 version older than advertised. This situation may occur after
  a new database version is published. The issue affected users downloading the
  whole CVD database file.

- Changed the default freshclam ReceiveTimeout setting to 0 (infinite).
  The ReceiveTimeout had caused needless database update failures for users with
  slower internet connections.

- Correctly display number of kilobytes (KiB) in progress bar and reduced the
  size of the progress bar to accomodate 80-char width terminals.

- Fixed an issue where running freshclam manually causes a daemonized freshclam
  process to fail when it updates because the manual instance deletes the
  temporary download directory. Freshclam temporary files will now download to a
  unique directory created at the time of an update instead of using a hardcoded
  directory created/destroyed at the program start/exit.

- Fix for Freshclam's OnOutdatedExecute config option.

- Fixes a memory leak in the error condition handling for the email parser.

- Improved bound checking and error handling in ARJ archive parser.

- Improved error handling in PDF parser.

- Fix for memory leak in byte-compare signature handler.

- Updates to the unit test suite to support libcheck 0.13.

- Updates to support autoconf 2.69 and automake 1.15.
