Chun-Yi Lee 6852f6984b EmbeddedPkg/VirtualRealTimeClockLib: Support SOURCE_DATE_EPOCH
RISC-V ovmf used VirtualRealTimeClockLib but the default epoch is a
compilation time. It causes that the RISC-V ovmf binary image is NOT
reproducible.

This patch added the support of SOURCE_DATE_EPOCH by printenv command.
If SOURCE_DATE_EPOCH be found then we use it as BUILD_EPOCH. Otherwise
we run date command for setting BUILD_EPOCH.

For distributions want a reproducible RISC-V ovmf image, they should
export SOURCE_DATE_EPOCH environment variable before building ovmf.
