[EXEC] Fixed execing of scripts with no hash-bang
The function tryexec used the original name instead of the path found through
PATH search. This patch fixes that.
Test case:
trap 'rm -f $TMP' EXIT
TMP=$(tempfile -s nosuchthing)
cat <<- EOF > $TMP
echo OK
EOF
chmod u+x $TMP
cd /
PATH=${TMP%/*} ${TMP##*/}
Old result:
/bin/sh: Can't open filelgY4Fanosuchthing
New result:
OK
