    OBJ_bsearch_ex_(): Fix const qualifier warning with CHARSET_EBCDIC

    Fixes #31161

    When building with CHARSET_EBCDIC defined,the compiler warns about
    discarding the 'const' qualifier when assigning from base_[i * size]
    to the non-const pointer p1:

    `warning: assignment discards 'const' qualifier from pointer target type`

    Change p1 from 'char *' to 'const char *' to maintain const-correctness
    since the data being pointed to should not be modified through this
    pointer.

    Additionally, remove the unused variables l and h that were left over
    from a previous implementation of the fallback linear search. These
    variables served no purpose and only generated unused variable warnings.
