package/libgcrypt: replace reconfigure patch with upstream patch
The `ac_cv_sys_symbol_underscore` reconfigure patch was added to
Buildroot back in 2007 [1], but was not reported to upstream back then.
Meanwhile, the issue has been fixed upstream [2] after the version bump to
version 1.8.4.
In order to add another upstream patch, which will add a pkg-config file
for libgrypt and therefore requires autoreconfiguration as well, replace the
current patch with the upstream patch.
