v4l-utils: Fix QA and build errors related to _TIME_BITS on 32-bit

* Remove GLIBC_64BIT_TIME_FLAGS="" to enable _TIME_BITS=64 by default,
  which avoids the following QA issue during builds on 32-bit systems:

  WARNING: lib32-v4l-utils-1.24.1+git-r0 do_package_qa: QA Issue: /usr/bin/cec-compliance uses 32-bit api 'time'

* Undefine _TIME_BITS to fix the build error:

  /usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
