Romain Naour c0dcefa7ba support/testing: TestNoTimezone: fix the test case for Glibc 
We have changed to a Glibc based toolchain recently [1] but the
behavior of TZ handling is not the same between libc implementation
when no Zone Database is installed.

musl and uClibc-ng return "UTC" when the data file of the requested
time zone is missing or when TZ is not set.

 # TZ=America/Los_Angeles date +%Z
 UTC

 # TZ= date +%Z
 UTC

Glibc return all or part of TZ content or "Universal" if TZ is empty.

 # TZ=America/Los_Angeles date +%Z
 America

 # TZ= date +%Z
 Universal

As demonstrated by TestAllTimezone, Glibc return "PDT" when the
America/Los_Angeles time zone data file is installed:

 # TZ=America/Los_Angeles date +%Z
 PDT

Since the Glibc behavior seems weird (not a bug [2]) when TZ is
set but the time zone data file is missing, update our test
to check against a string defined in the Glibc code [3].
