bug#25501: sed-4.3: testsuite/runtest does not check for a program extension

[Juan Manuel Guerrero]

OFYI, the testsuite/runtest shell script makes the assumption that programs
like get-mb-cur-max and test-mbrtowc have no extension but this is not true
for non-posix systems like Windows (aka MinGW) or MSDOS (aka DJGPP).  Thus
the check fails when runtest is invoked.  In some way the possibility for
an extension should be provided.  The patch below is not intended as fix,
it shall only demonstrate the issue.  It is clear that this problem cannot
be reproduced on a posix system like linux.
This means that the test fails to find programs if they have an extension
like ".exe" as used to be in DOS/Windows.

Regards,
Juan M. Guerrero
