New FNAL agents failed to check the proxy lifetime
**Impact of the bug**
WMAgent

**Describe the bug**
Jen reported during the P&R meeting that 2 of the FNAL agents had proxy error in WMStats (submit3 and submit4), which are running the newest WMAgent version 1.2.6.patch1. The other FNAL agents are doing just fine, running on the old version.

Checking the lifetime of my proxy, I see everything is fine:
```
notBefore=Sep 19 05:50:03 2019 GMT
notAfter=Sep 26 05:55:02 2019 GMT
```

**How to reproduce it**
none

**Expected behavior**
Properly fetch the proxy timeleft and properly report it ;)

**Additional context and error message**
It might be coming from one of the security/crypto libraries that have been updated in cmsdist/comp over the last month or two...
