RFR: 8351138: Running subset of gtests gets error printing result information [v3]

[SendaoYan]

> Hi all,
> 
> This PR fix the makefile bug when there is no gtest 'disable tests' then report syntax error.
> 
> Before this PR makefile used below command to get the 'disable tests' number, when there is no 'YOU HAVE [0-9]+ DISABLED TEST' string line in gtest result file gtest.txt, this gawk command will not print anything, so shell report syntax error later.
> 
> 
> gawk '/YOU HAVE [0-9]+ DISABLED TEST/ { if (match($0, /[0-9]+/, arr)) { print arr[0]; found=1; } if (!found) { print 0; } }' build/linux-x86_64-server-release/test-results/gtest_Align_server/gtest.txt

> After this PR makefile will use below command to get the 'disable tests' number.
