[OS-BUILD PATCHv4 4/4] [redhat] egit.sh: simplify, add use case

[GitLab Bridge on behalf of bcrocker]

From: Ben Crocker

Simplify the case statement to only the git subcommands we actually
provide overrides for.

Usage:

GIT=<path to egit.sh> EGIT_OVERRIDE_DESCRIBE=v5.9-rc8 DIST=.elrdy make dist-srpm
GIT=<path to egit.sh> EGIT_OVERRIDE_MERGE_BASE=<sha1> DIST=.elrdy make dist-srpm
