ctype: Fix integer type for caseconv_entry::delta
The commit 46ba1675c457324b0eeef4670a09101ef3f34c50 accidently changed a
bit-field from signed to unsigned. The caseconv_entry::delta must be a
signed integer, see also "newlib/libc/ctype/caseconv.t".
Unfortunately, a standard GCC/Newlib build is done without
-Wsign-conversion. Using this warning option would have helped to avoid
this bug:
caseconv.t:2:22: warning: unsigned conversion from 'int' to 'unsigned int:17' changes value from '-32' to '131040' [-Wsign-conversion]
{0x0061, 25, TOUP, -32},
