fault-injection: fix failcmd.sh warning
"fault-injection: add tool to run command with failslab or
fail_page_alloc" added tools/testing/fault-injection/failcmd.sh to make it
easier to inject slab/page allocation failures by fault injection.
failcmd.sh prints the following warning when running with arguments
for command.
# ./failcmd.sh echo aaa
failcmd.sh: line 209: [: echo: binary operator expected
aaa
This warning is caused by an improper check whether at least one
parameter is left after parsing command options.
Fix it by testing the length of $1 instead of $@
