vim: remove build timestamp/hostname/username

Build timestamp prevents reproducible builds [0].
Same for other irrelevant informations e.g. hostname, username.
Thanks to debian for the patch.

Subject: Support defining compilation date in $SOURCE_DATE_EPOCH
There is an ongoing effort[0] to make FOSS software reproducibly
buildable. In order to make Vim build reproducibly, it is necessary to
allow defining the date/time that is part of VIM_VERSION_LONG as part of
the build process.
This commit enables that by adding support for the SOURCE_DATE_EPOCH
spec[1]. When the $SOURCE_DATE_EPOCH environment variable is defined,
it will be used to populate the BUILD_DATE preprocessor define.
If BUILD_DATE is not defined, the existing behavior of relying on the
preprocessor's __DATE__/__TIME__ symbols will be used.
