[LTP] [PATCH] numa01.sh: fix error in getting number of CPUs

[Simon Xu <xu.simon@oracle.com>]

test04 in numa01.sh is using a wrong method to get the number of CPUs.
This results in:

numactl: cpu argument 9 is out of range

awk: cmd. line:1: fatal: cannot open file `/proc/4116/stat' for reading
(No such file or directory)
/opt/ltp/testcases/bin/numa01.sh: line 475: [: =: unary operator expected
awk: cmd. line:1: fatal: cannot open file `/proc/4116/stat' for reading
(No such file or directory)
/opt/ltp/testcases/bin/numa01.sh: line 481: [: -ne: unary operator expected
/opt/ltp/testcases/bin/numa01.sh: line 488: kill: (4116) - No such process
numa04      4  TBROK  :  Kill on process 4116 fails

Fix it by getting number of CPUs by grepping /proc/cpuinfo.
