tools/asn1_compiler: avoid -Wdiscarded-qualifiers

Browse Source 
Building with GCC 15.2 results in warnings:

    tools/asn1_compiler.c: In function ‘tokenise’:
    tools/asn1_compiler.c:442:37: warning:
    assignment discards ‘const’ qualifier from pointer target type
    [-Wdiscarded-qualifiers]
      442 |             dir = bsearch(&tokens[tix], directives,
          |                 ^

    tools/asn1_compiler.c: In function ‘main’:
    tools/asn1_compiler.c:632:11: warning:
    assignment discards ‘const’ qualifier from pointer target type
    [-Wdiscarded-qualifiers]
      632 |         p = strchr(grammar_name, '.');
          |           ^

bsearch() is defined as

       void *bsearch(size_t n, size_t size;
                     const void key[size], const void base[size * n],
                     size_t n, size_t size,
                     typeof(int (const void [size], const void [size]))
                         *compar);

* Use the correct type for dir.

strchr() is defined as

        char *strchr(const char *s, int c).

* Use a conversion for the assignment to p.
