toolchain-glibc.eclass: avoid using KV_to_int and get_KV

'KV_to_int' and 'get_KV' are portage internals.

This change pulls in implementation of 'KV_to_int' and
'get_KV' as-is with a rename:
    KV_to_int -> tc_glibc_KV_to_int
    get_KV    -> tc_glibc_get_KV (small API change)

Closes: https://bugs.gentoo.org/587320
