populate_sdk_base, adt_installer_internal: fix issue on older distributions

This patch addresses an SDK installer issue on older distributions if
the installation takes place in another directory than the default one. In
fact, is all about the 'file' utility version used for determining if a
file is a text file. For example, for a perl script, newer 'file' versions
return:
"...script, ASCII text executable"
while older versions return:
"...script text executable"
Hence the regex pattern didn't match the scripts.

Also the patch contains two unrelated minor fixes:
 * return an exit code of 1 instead of -1 when installation machine is
   not supported. That because on an older distribution we also get this
   error message: "exit: 9: Illegal number: -1";
 * remove unnecessary $SUDO_EXEC prefix to grep;

[YOCTO #3538]
