ltmain.in: Fix mistaking a directory as an executable
find_executable() can return a directory of the same name as the target
executable if the directory is found earlier in the PATH, which causes
check_executable() to fail.
Reported: https://savannah.gnu.org/support/?111191
* build-aux/ltmain.in: Check if directory is found before executable
in the PATH.
