package/glibc: update hash of LICENSES file for ARC version

package/glibc: update hash of LICENSES file for ARC version

In commit 5d4f23cbe65c79826b1b2071e972803a453934cb ("toolchain: Bump
ARC tools to arc-2018.09-rc1"), the glibc version for the ARC
architecture was bumped, but the hashes of the license files were not
updated accordingly, causing a build failure during "legal-info":

ERROR: LICENSES has wrong sha256 hash:
ERROR: expected: 61abdd6930c9c599062d89e916b3e7968783879b6be0ee1c6229dd6169def431
ERROR: got     : 35bdb41dc0bcb10702ddacbd51ec4c0fe6fb3129f734e8c85fc02e4d3eb0ce3f

The changes between the previous LICENSES file and the new one are:

 - The text related to libidn has been removed from the LICENSES file,
   following the switch to libidn2:

 - The text related to stdio-common/tst-printf.c has been removed from
   the LICENSES file, following the removal of this non-free code from
   glibc:
