[Buildroot] [PATCH 1/2] package/msmtp: drop unneeded static openssl workaround

[Fabrice Fontaine]

msmtp uses pkg-config to find openssl dependencies such as lz or latomic
so drop unneeded openssl workaround that was added by
https://git.buildroot.net/buildroot/commit/package/msmtp?id=468bbc1538aaea87beaf455a2ad6ea5a255d5f58

I don't know why it was added seven years ago as msmtp already used
pkg-config at this time:
