clamav: remove stray \ which was masking FAKE_FLAGS

Log message:
clamav: set OBJC="${CC}" to use clang on clang arches, rather than
trying to auto detect, which picks up gcc on those base-clang arches
which still install gcc (which I think is now causing more problems
than it solves).
Fixes a build problem reported by solene@ on i386 with old /usr/bin/gcc
present after the installer auto-removed old gcc-libs.

MFC clamav update, DoS in PDF, out-of-bounds read in ARJ

Log message:
update to clamav-0.102.3
- [CVE-2020-3327](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-3327):
Fix a vulnerability in the ARJ archive parsing module in ClamAV 0.102.2 that
could cause a Denial-of-Service (DoS) condition. Improper bounds checking of
an unsigned variable results in an out-of-bounds read which causes a crash.
Special thanks to Daehui Chang and Fady Othman for helping identify the ARJ
parsing vulnerability.
- [CVE-2020-3341](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-3341):
Fix a vulnerability in the PDF parsing module in ClamAV 0.101 - 0.102.2 that
could cause a Denial-of-Service (DoS) condition. Improper size checking of
a buffer used to initialize AES decryption routines results in an out-of-
bounds read which may cause a crash. Bug found by OSS-Fuzz.
- Fix "Attempt to allocate 0 bytes" error when parsing some PDF documents.
- Fix a couple of minor memory leaks.
- Updated libclamunrar to UnRAR 5.9.2.

- Multiple memory leaks were found in ClamAV that could possibly allow
attackers to cause a denial of service via excessive memory consumption

have an unknown impact and attack vectors related to file descriptor

and other small bugfixes have been made. The new option "--on-outdated-execute"
allows freshclam to run a command when system reports a new engine version.
