Subject: [PATCH] qcacld-3.0: Add microseconds to BUILD_TAG

Some of the post processing tools need high resolution timestamps in the
build tag to differentiate WLAN driver modules in the same build. Add
current time with nanoseconds rounded to the first 6 digits, which is
microseconds. Also fix the 'date' command format.

e.g. date -u +'%F %T.%N %Z'
