ash: make EPOCH variables work if RANDOM is disabled

Commit 1d37186fe2 (ash: add bash-compatible EPOCH variables) added
support for the EPOCHSECONDS and EPOCHREALTIME variables.

These variables are dynamic and therefore require the VDYNAMIC flag
to be non-zero.  However, this is only the case if support for the
RANDOM variable is enabled.

Give VDYNAMIC a non-zero value if either EPOCH variables or RANDOM
are enabled.
